Hello,
Welcome to the forum and I am glad to help you out. From the symptoms the possibility of granuloma annulare needs to be ruled out. Granuloma annulare consists of reddish bumps arranged in a circle or ring which are itchy.
Usually it is asymptomatic but due to cosmetic disfigurement topical or oral steroids may be needed. I suggest you to discuss this possibility with your dermatologist.
I sincerely hope that helps. Take care.
