See a doctor and get tested if you have a concern. Can't diagnose symptoms over a computer.
Do they burn? I got a stinging rash on my forehead that appeared out of nowhere one day. I only checked for it because I felt stinging on my forehead.... Like irritation. It then spread down my face. But the rest didn't really sting or anything, only in the area of the initial outbreak. I had a rash prior to that which was unnoticeable, but that carried no sort of pain or itching. Both were on my face. To me these were the most conclusive symptoms. My exposure was somewhat low risk, but I feel she may have cut me with her nails at one point whic could have created a point of entry. I tested today and will get my results next week. I'm less afraid than I was before after learning more about this disease, but I'd of course prefer to live without it if I can.
See your doctor. ARS rashes don't itch.
