Sounds like a drug rash
Hello, I'm Dr. Branch, thanks for using Ask a Doctor service
The rash you describe sounds like it could be an allergic reaction to a medication or something you ate. Almost any medication can cause a drug rash, usually in the first couple of weeks after starting the medication, but it can occur at any time. Other possibilities would be a viral infection, or possibly eczema.
If the rash is bothering you at all, you could try using some 1% hydrocortisone cream to help with the dryness and itching.
If you want to send a picture or let me know what medications you are currently taking, I may be able to speak more specifically about what might be causing it.
I hope that helps answer your question, please let me know if you have any other questions or anything else I can help with.
