I have a rash on my right forearm that itches terribly.  There are also spots that are bright red where the skin has come off.  I have tried creams for itching and even an antibiotic cream but nothing seems to work.  I can also feel the rash underneath the skin but cannot see it all.
Hi, It could be a popular urticaria. Popular urticaria is commonly due to an allergic reaction to an insect bite. You could apply a calamine lotion and an antihistamine tablet for a week. If your symptoms do not improve after a week, you should consult your Dermatologist. Hope I have answered your query. Let me know if I can assist you further.
