Tiny red dots on wrist and rash on arm

[u/Long-Pen-8200]

I am F(21), i weigh 121 lbs and 5’3”, and I’m relatively “healthy” for the most part. I say that because

I have random episodes where my body would collapse on me, and my legs would tingle very badly and sometimes my arms would not work with me, but there’s no diagnosis I have done every test and everything has come back good. (mri, ct, lp, and lots of blood work)

December of 2025, I had a rash appear on my right arm and it won’t go away. I went to the doctor for it and he gave me a steroid/antifungal cream and I applied that for two weeks and it hasn’t done anything to it. Yesterday, on my left wrist, a few red dots appeared and more dots have appeared today. The dots appeared after my carpal tunnel pain flared up. I tried searching it up but no answer :(, and I don’t have the money to see a dr and do more tests and get no answer

You likely have some type of dermatitis, but not enough information is provided to determine the exact type.

whenever my carpal flares up, that area gets really warm and a bit reddish. the dots have a more burning sensation as well. I hadn’t applied any product or perfumes in that area, and didnt wear anything around my wrist either.
