I recently got chicken pox but it was fully cured. Post that, I got a some skin rashes under my right breast. It started like few dry blisters but then spreas across and became slight itchy. Now the rash has spead across the area below breast and also on the lower/bottom are of the breast. The rash looks like brown dry blisters. The area has become slight itchy and skin has become rough. I have attached photo of my rash. Please advise.
