A: Yes, the biggest thing is to remember everything about your rash and what you’ve tried.
Where did it start?
Did it move to different parts of your body?
Have you had this rash before?
Does anyone else in the house have a similar rash?
In terms of treatments, what helped and what didn’t, don’t use cortisone before your evaluation because it could make the rash appear different and it could delay a biopsy if medically necessary. If itch is a part of the rash, over the counter sarna (or something else similar without a steroid) is recommended to soothe that itch.
