Hello doctor I have an allergy on my skin from two years.started with fingers and elbow and neck . It was there for around 6-7 months and then cleared but in this mean time same issue started on legs . And i thought will get normal in same time but it's around 1.5 years ..and m unable to understand why this allergy is not going and also it's increasing now. I just used one ointment Desonide. Earlier was working now this cream also not useful. Please see the pics and suggest what to do ??
