I'm a 25 years old male. I've been having pus coming from my two armpits for a over a year. The doctor told me that they will go away by themselves. A month later one armpit was ok. Now i have a problem with small blisters on my scalp after changing my shampoo. but it has been like this for over a month. I also started having small blisters that come and go on my nose. I saw a dermatologist yesterday and he told me that the skin in armpits, scalp and face are related and that i have a superinfection and gave me an antiobotic for a week. If i don't get better he said he will do biopsies from these blisters to determine the right treatment. Does that sound logic and familiar?
