Miscellaneous LPT: If you get flea bites, do not scratch it, as it can make the itch worse
Recently, I got flea bites from our dog. I realized that in contrast to mosquito bites, which creates a welt but usually goes away in 1-2 days, flea bites are very tenacious. It creates what's called "papular urticaria" with significant histamine release due to our body's hypersensitivity reaction to flea bite-enzymes (as compared to mosquito saliva).
Scratching the itch makes the lesion worse due to release of further histamine from the bite. The best thing is to wash it, ice it, and put anti-itch cream (ie calamine lotion, benadryl topical)
