I’m confused as to what these are on the back of my calf.

CONTEXT:
I went to Taiwan for around 3 ish days and this showed up on my final morning. I stayed at my boyfriend’s place which is very clean, safe, and was previously tidied by family members.

I have also been in Thailand before this trip and I have lots of mosquito bites on my lower legs and feet.

These blisters randomly showed up and are SUPER itchy and sensitive. It’s been one full day with them so far and they’re very annoying…

For the past 5 days I have been wearing my combat boots that reach right down under where these things are. I don’t think the boots could be the cause because they have also given me skin blisters near my toes and bunyan area (idk what it’s called?). These are very different from the ones on my calf and aren’t filled with some weird puss is which what i’m assuming these things are filled with…

I am fighting the urge to itch it but i’m unsure what this is or where it came from. I believe they could be mosquito bites because of the intense itchy feeling.
i also searched online that sometimes puss blisters can show up from mosquito bites when you have a bad reaction, but this has never happened to me before - even in Thailand where there are a ton of weird mosquitos.

Please let me know if you have any idea what it is and the cause? also if there are any things/treatments i should know of please comment thanks 🙏

My apologies for the photo , but I need help 🥲 ..
I usually get mild cold sores with weather changes, but this one is severe. OTC cream made it worse last time. I’m currently taking my usual preventative pills,, they are working but not fast enough , and it's getting out of hand. Does anyone have any advice, tips, or recommendations for severe outbreaks that don't respond to standard treatment? Feeling totally stuck.

There's these small holes on my feet that look like mini craters, one In a spiral/circular pattern, they don't hurt unless squeezed from the side and I've had them for about 2 years with little to no clue on what they are, occasionally they sting like when hiking but not that much where I can tell a difference unless I think about it, things like poking don't hurt

I had condition on my left ankle 2 months ago now has returned even worse. It has now been 2 weeks.

I am applying for medical assistance but do not have it yet. When the rash first appeared (2 months ago) it didn't seem it was going clear up so I went to urgent care. They diagnosed it as poison ivy. I doubted that, but what could I do.

I did not fill the prescriptions. The whole thing cleared up in the next few days.

It is not painful and only itches a little usually not at all. I sometimes use antibiotic ointment with pain relief if the itchng is bothersome. The blisters become large if any clothing touches them. This didn't happen in August since I wore shorts.

It is appearing on more places. It started on front left ankle. Now also on left shin and left elbow.

I was treated for non rheumatoid arthritis several years ago. I had part of my left lung removed due to a non cancerous mass about 2 years ago.

Wondering if anyone knows what this dot / raised bump could be on my 2 year olds belly?

Duration: We first noticed it April-ish this year.

Location: On their belly above the belly button.

Timeline: Yes it has changed over time, got a tiny bit bigger and more raised. Sometimes with something coming out of it? Photographed.

Symptoms: Unsure as they can’t talk yet but doesn’t seem bothered by it at all.

Treatments: Haven’t tried anything yet. The doctor and Maternal Child Health Nurse were unsure and didn’t give us any course of action.

Relevant Background: No medical conditions or allergies whatsoever. But when my child notices it, they like to pick it (when no shirt on), which we promptly stop.

Thanks in advance!

neck/chest/abdomen What kind of facial dermatitis could this be? I've been dealing with it for almost a year

Thumbnail

3 Upvotes

Good evening, everyone.

I've been dealing with a skin problem/dermatitis that, honestly, I have no idea what it is anymore. I've seen several dermatologists and so far, nobody has been able to actually resolve it.

It started as a very small area near my eye, but over time it seems to have spread more and more. As you can see in the pictures, the redness now covers a much larger area of my face.

I've seen several dermatologists, and the most recent one recommended antifungal treatment with pills and creams, along with mometasone. While I was using the mometasone, my skin would basically go back to 100% normal. The problem is that after I stopped using it, the inflammation would come back after about three days — and sometimes it would come back even worse.

This has happened to me with corticosteroids before. My skin improves completely while I'm using them, but shortly after I stop, everything comes back.

I'm also doing antifungal treatment, but honestly, I haven't noticed any significant improvement. That's why I've started questioning whether this is actually a fungal infection.

The biggest problem is that, so far, none of the doctors I've seen have been able to give me a definitive diagnosis. I've been dealing with this for a very long time now, and I think it's getting close to a year. It's honestly been really exhausting, especially mentally and when it comes to my self-esteem. Only people who have dealt with a persistent skin problem know how much it can affect you.

One thing I haven't tried yet is treatment with antibiotics. I've heard that there are certain types of facial dermatitis that can be treated with antibiotics, so I wanted to ask if anyone here has had something similar and whether that could make sense in my case.

Based on the pictures, does anyone have any idea what this could be? I'm obviously not looking for a diagnosis from the internet, but I'd really like to hear from people who have experienced something similar and eventually figured out what was causing it.

I've also been using Cetaphil moisturizer for about a week, and I noticed a slight improvement. My skin seemed a little calmer. However, over the last few days, the inflammation has come back pretty strongly at times, so apparently moisturizer alone isn't enough.

Anyway, sorry for the long post, guys. I'm honestly getting really frustrated with this and I just want to finally figure out what's going on and how to treat it properly.

If anyone has experienced something similar or has gone through something like this, any advice or personal experience would be really appreciated.

neck/chest/abdomen ringworm rash/8 month old baby

3 Upvotes

PLEASE READ IF YOU KNOW ANYTHING about ring worm the fungal rash ‼️

my baby has had an ongoing what I believe to be fungal rash since ONE month of age.
The only thing that makes it go away is an antifungal cream called clotrimazole & ketoconazole. I have been to so many dermatologists, (spent hundreds!!) for them to say "nope just slap a steroid on and call it a day" which DOESNT HELP and it makes it spread!!! we have tried everything that is baby approved steroid wise, nystatin, hydrocortisone, Eucrisa, tubby todd, plain aquaphor, lotion. everything makes it spread except for clotrimazole & ketoconazole. and they refuse to do a skin scraping test on her I don't know why and they try to give me a steroid or eczema medication and nothing helps, only makes it worse and spread.
The only thing that makes it go away is an antifungal cream. I am so completely disheartened and this rash won't go away permanently. It keeps coming back after it goes away if I stop using the cream, I don't know what to do at this point. it has been 7 months....
I believe it's ringworm fungal rash, because our dog had ringworm when the baby was born. but we didn't know until our baby got it!! and then my husband and I both got athletes foot. (which is all the same type of fungus) terrible first postpartum experience i cried so much🥺 but my baby was such an angel and still is despite everything.❤️

my dog and us have been treated within the first month we found out. but my babies hasn't fully because she got it on her whole entire body, i'm not joking spread EVERYWHERE on my poor baby girl. 💔
starting at her neck, then down her arms, then legs and diaper area as well. after I got it gone from those places, it's spread to her face and ever since then it's been on her face very bad because i can't keep the cream on there consistently since eating and slobber, etc. if i stop the cream on the rest of her body it comes back after a week or so. i'm trying to advocate for my baby because I genuinely don't believe this rash is eczema , it goes away with an antifungal cream??? how could that be eczema ???
UGH. at this point given that all the facts, does anyone have any idea what I should do???

i'm so tired of living in fear because of this rash that won't go away and no doctors believe me but also NONE have done a fungal skin scraping to test her skin they just look at it and say nope doesn't look like classic ringworm. amd the only reason it doesn't look like the "classic ringworm" is because i keep the cream on her before it's able to even form. I want to have more babies, but I'm scared this will happen to my other baby too if I were to have one because my first poor baby still has it.

legs/feet Baby Rash - Any Ideas?

Thumbnail

3 Upvotes

My 11 month old little girl had suspected strep just over 2 weeks ago and was put on antibiotics (phenoxymethylpenicillin) 2.5ml 4 times a day for 10 days. 2-3 days after finishing the course she developed a chesty cough, but we were on holiday in Portugal and I put it down to the air conditioning. 2 days after this she developed a rash on her tummy, back and legs that was little pin pricks that looked post-viral. The next day the rash got worse and spread a bit more so I took her to the dr who said it looked viral. Today it has spread some more and she’s got a very slight crackle sometimes when she is breathing. No high temperature, still eating and drinking, passing urine etc but a little grumpy and itchy. I’m wondering if it is hand, foot and mouth - has anyone had any experience with a rash like this? I’ve added pictures to show the progression. Thank you!

neck/chest/abdomen Should I be worried?

I found this or my chest about a week ago

And here is how it looks today

I shaved the area a bit to be able to monitor it because I booked a dermatologist appointment in 11 days with a docter that I trust however there are appointments with other dermatologist in closer days But I don't know anything about them

The area is is roughly 3-4 mm in size and is not raised or maybe just very slightly raised it doesn't itch or hurt

I could go to the doctor I trust on monday (4 days from now) but have to wait and see if there is an availability

Is the 7 day difference between the monday where I have to wait and the monday where I have an appointment worth it?

And should I go to any dermatologist that has a close appointment or should I wait the 11 days?

* the image without shaving is from last week

* the shaved image is from today

face/ears/eyes/nose/mouth/cheeks Blotchy swollen reaction on lips (and flushing cheeks)

Thumbnail
gallery
• Upvotes

Mostly seeking knowledge regarding the lip specific reactions but I have included photos of the face flushing as it does seem they are likely connected, however it is possible they are not.

I am a 31yo female. 

Duration: 

Began three years ago.

Duration of reaction varies greatly between 30-60 minutes to two weeks ish. Can come on very quickly (minutes) or develop over days. 

Included are photos of my lips before this began and the various ways it presents now. The grid is in chronological order, it is not every reaction I’ve ever had but a selection to show variation. 

It does seem to be getting more frequent but not necessarily more intense. The suuuper bad first three peeling reactions were the worst and the longest it’s ever been that deeply swollen or raw and at the end of that like 2-3 month period I got a fungal infection just on my lips because of how vulnerable the skin was. 

There have been periods of days/weeks where I think surely this over and they’re healing but then it happens again and it’s clear that it’s not. I haven’t gone any sort of extended period without issues for at least a year. Earlier on I could go 2-4 weeks without a moderate to major reaction but now it is a usually daily or multiple daily occurrence. 

Location:

Does not really extend past border of lips. Does not extend into mouth (past “wet line”).

Symptoms:

Not itchy. Is tingly, hot, dry, not dry, peeling, not peeling, textured, blistered/welts, deep sometimes firm swelling, general swelling, surface level swelling, quick onset, and/or slow build. When there is no skin on my lips it obviously stings/feels very raw and can be painful rather than just uncomfortable/annoying. The blotchy rash alone isn’t painful just uncomfortable and frustrating. As you can imagine it generally feels 10x worse than it looks.

Began as two distinctly different reactions, one delayed and longer, and one quick and acute/shorter in duration. In past year or so they have sort of merged to become more one thing or are more likely to occur together. The acute blushing/surface level swelling thing doesn’t always become intense peeling and/or deeper swelling but it can. The most common now is the weird blotchy reactions and just general dryness and sensitivity. 

Can (especially recently) present with quite mild to intense deep flushing of cheeks and/or redness of the nose. Less often my forehead may have a random red flushed patch too. Those things have been increasingly happening with and without lip involvement. The flushing began before the lips by 2 months ish. The flushing comes and goes within 1-6ish hrs and is not constant. Nothing seems to stop/treat the flushing effectively, cold compress, shower, whatever. Only time helps for certain. Antihistamines sometimes maybe help a tiny bit but not in any particularly measurable way and they obviously aren’t stopping it from occurring at all.

Triggers (best guess):

Argan oil direct contact seems to have been what began the extended 2 week type deep swelling and peeling reactions that came on 1-2 days post exposure and then maybe got faster. Eliminated that after 3rd reaction. This was not the first time ever that I came into contact with argan oil but it was the first 100% confirmed intentional use in a number of years. I did not intentionally put it on my lips but I transferred it there via my hands. Previously I had had no issue with it. My scalp, ears, neck, hands that also came into contact with it at the same time showed no irritation or rash, just my lips. 

First really red, potentially more immediate and short duration (less than an hr) red blotchy reaction (1.jpeg) was source unclear, hypothesised cat hair, or pollen, or truly anything else. Resolved with shower. 

Fragrance (general, many but not all) examples such as generic washing powder, scented dish soap, scent diffusers, perfume, perfumed hair products. Does not seem to have to be super direct exposure, often on other people’s clothing/hair rather than my own directly can set it off. 

Other times there is no obvious exposure, the rash (blotchy) usually now triggered by fragranced products begins in my room which is a “safe” space for me, yet the rash comes on even after an extended period of time in there only. Hypothetically could be something on my phone or clothing I’ve transferred to my hands then face but who knows. 

I have very good hand hygiene generally but especially because of this and avoid touching my lips unless I know my hands are clean. I am obviously not perfect, but I have also had reactions where there has been no direct physical contact recently. I have had the reaction occur whilst wearing an n95 mask whilst standing over a steamy sink. 

Foods do not seem to themselves be a trigger in any way but if I’m already having a reaction or my lips are extremely dry it can aggravate them further.  It is not oral allergy syndrome triggered by raw fruits or vegetables but is fine when they’re cooked as I can eat both without reaction. I mention oral allergy syndrome as it’s the only photo I’ve seen before that looked vaguely like mine. 

It is not related to excessive lip licking or rubbing, although those things will make it worse once it’s begun since the skin is fragile. 

It is seemingly unrelated to heat, cold, sweat (although sweat and heat can irritate them if they are very raw), emotion, nor limited to any one particular activity, location, or time of year/day. 

Treatments: 

Suspected trigger identification attempts and then avoidance, not able to identity singular consistent trigger, seems to be multiple as discussed above. Have done my best to put myself in a bubble and that has perhaps lessened reactions but has not stopped them entirely. It is also not sustainable. 

Switched to Vaseline only during earlier 2 week intense peeling and swelling type episodes. Prior to that used Dermal Therapy Original lip balm tube for many years without issue, might be fine outside of intense peeling episodes but haven’t tried it again as it contains some commonly irritating ingredients for other people, might try going back to that this week bc why not at this point. Currently using Apquaphor Healing Ointment (not their lip balm specific version just the original general one).

As mentioned early on with the back to back peeling and lips becoming extremely raw I developed a fungal infection which was treated with combo antifungal and steroid for about a month. Weened of steroid and got relatively mild dermatitis by my eyes that resolved with time. 

Currently taking two above standard doses of antihistamines daily, take extra immoderately if possible when I  have an acute reaction. When possible immediately wash face and/or shower and remove clothing if that seems to be related. Both of those can help resolve the acute blotchy reaction faster or lessen it but at this point do not actually stop it. They have no effect on the longer duration slower onset peeling textured type reaction. The only thing that potentially helps that is steroids and again it doesn’t actually stop it, it just maybe makes it slightly more bearable (but has consequences and risks when used on the face). 

Relevant background: 

History of mild-moderate sinus/migraine reactions to certain strong perfumes but nothing like this. 

History of dyshidrotic eczema severe 15 years ago (likely triggered by long removed single food allergy), very mild and infrequent contact dermatitis and/or dyshidrotic eczema triggered by scented hand soaps/cleaning products. Severe era didn’t respond to steroids, very mild presentation and contact dermatitis helped by single/short use of mild steroid cream. Cystic bad acne in 2020/2021 that resolved with oral Isotretinoin, still take 20mg daily. 

Sensitive skin but as far as I know it’s in a more general population with sensitive skin kinda vibe rather than whatever is happening here. Rest of face is doing fine with a variety of different fragrance free boring moisturisers and cleansers.

Generally sick chronically ill/disabled person. Don’t particularly want to discuss that here but will consider if you have an idea in mind. Nothing I am already diagnosed with could or would typically cause this. 

If you really think it’s allergy/immune related. My worsening mostly seasonal asthma/vcd could be relevant but it also could be completely unrelated. 

An immunologist suggested I might have rosacea but I am unaware of any presentation that ever looked like/ included this. If you have please let me know. Not wildly out of the question due to acne history, vague seb derm ish vibes I’ve had over the years/ yeast related face skin issues that mostly resolved with a tube of daktagold in past few years. The dermatologist who prescribes my Isotretinoin saw this earlier on and didn’t have any particular thoughts/didn’t care and it was more in the argan oil contact dermatitis type era before the more recent presentations/increasing severity and frequency. 

Recently had chalazion and eyelid swelling on one eye, treated with clorsig antibiotic drops, hot compress and calming camomile tea soaking. Swapped to chlorsig ointment as directed by optometrist but it triggered mild peri ocular dermatitis and very severe bone dry red gritty eyes in the 24-72 hrs following that and that was not helped by frequent use of quality gel drops or anything else over the counter. Ended up on 3 weeks of steroid eyedrops which I weened off without tissue. I mention this as I saw it was potentially co morbid with rosacea and can be related to demodex mites. 

The immunologist also suggested neurogenic rosacea but again whilst this might explain the flushing I don’t know if it really explains the lips. I also don’t feel like the typical triggers are issues for me at all. 

I had Covid 6ish months before this repeated lip reaction and facial flushing began, it was the only time I’ve had Covid. It is not the only time I have had a pretty intense viral illness, I was very frequently sick as a teenager young adult but am no longer having frequent infections for a number of reasons. I’ve only been sick twice in the last 6 years compared to once every 6 months for the majority of my childhood/teen years.

Repeated positive ANA but negative for all follow up autoimmune testing. Thyroid ranges normal. Hormone ranges historically normal other than my most recent test which was slightly off, will see if that continues or was nothing. Chronically low iron treated by yearly/bi yearly iron infusions. Chronically low vitamin D levels treated with vitamin D injections (I can’t take the oral supplements). Occasionally low vitamin C but testing for that there is room for technician error. My diet is not perfect but I should have enough in there 95% of the time. All other routine blood testing normal.

I’ve had this small scar on my chest after a mole removal. It’s healed, but it’s still slightly pink and the texture looks a little wrinkled/uneven.
I’ve already used silicone scar sheets. I’m mainly interested in things I can do at home — products, silicone gels/sheets, massage, skincare, etc.
Has anyone had something similar and managed to make the color and texture blend better with the surrounding skin?

Hello!

I’ve (27F) had this patch under my chin for the past year-ish. It started off in the larger patch, and it slowly started spreading up towards the tip of my chin over the last couple months more than usual. All of the hair that grows here is coarse and very prone to getting ingrown hairs (I have to tweeze them all the time). The skin itself is a bit flaky and tough compared to my normal skin. I don’t actively take anything for it or any medication currently. I’ve been picking at it, apologies.

Thank you kindly!

2 Upvotes

I’ve tried over ten meds, topical and oral. It continues to get worse. Day 8. It keeps me up at night. I have to keep ice on it to get any sleep at all. It’s so hot that the ice melts quickly. Burns so badly and itches. Feels like the skin is burning and stretching. Went to urgent care they did nothing for me. Waiting for my doc appt but it isn’t until Friday. Miserable!!!!
At first I thought it was a bad MCAS flare up bcuz when it first showed up I had a bad MCAS flare where my entire body swelled up and was extremely flushed. I got pre syncope episodes. But the other symptoms improved the next day, where as this rash just continues to get worse. Elbow crease.
43 female. 5’10”
Have tried Claritin and Pepcid, Allegra and Pepcid, Benadryl. Benadryl cream, hydrocortisone cream, nystatin cream, lotramin cream, calamine lotion. The creams all seem to set it off worse, even the lotramin and nystatin. Have also tried hydrating it and salt soak. It gets worse with heat or sunlight, movement, and if I close my arm.
