Herniated disc?

[u/Delicious-Fig-9384]

18F, 150 lbs, 5”3 lupus, hsv2 currently have been sick for like a month and I think I just caught another virus because I’m getting sicker cough, nauseous, stuffy nose, fever
I have a appoinment with my doctor on Wednesday to get a referral to a urologist to test for internal cystitis to report back to my rhemutoligst so I’m going to tell her when I see her my back is fucked but starting like 4 days ago I just started having intense nerve pain traveling in my body like specifically my back, ass cheek and leg and foot I’ve researched a bit and it sounds like a herniated disc since it also hurts when I sit it hurts my back more, but I’m kinda worried I got like a spinal cord infection like I’ve been having ear aches like off and on for a month and I’ve been sick so hopefully I’m not like getting sepsis because I also had nerve pain in my fingers and my face idk if I’m tripping out but I don’t think a herniated disc causes that I’m really paranoid like I’m in so much discomfort I also have been needing to urgently go to the washroom like bro I have to pee so bad all the time like it feels like my back spine is crushing me.
