My son had pink color skin rash/blisters in his left posterior ankle region for two weeks. My wife was applying turmeric and cider vinegar, it was getting healed. But after 1.5 weeks he was getting small dot like blisters in his butt. We showed him to a dermatologist. He was given benzoic acid cream, Emoist moisturizer cream, montecet tablet. We applied moisturizer twice a day (mor & Eve). Applied benzoic acid cream in night. Gave tablet in night. After two days, today he got small dot like blisters throughout his body. The few in his butt which was earlier got little big. It's itching for him. Please advice.
