Problem is only about 3-4 people ever really answer questions here and most of the people who post questions get there answer and leave. So your stuck without an answer. So I want to get you to a spot where they may be able to halp you more, so that is why I directed you over to Men's Health.
ok.. just thought someone might know from thinking a blister was an std and then it turned out to not be one.
This is a STD community, maybe try posting in Men's Health
ok, does anyone else here know of a non-std cause of blsiters?
Only other advice I have is to folow up with your Dr.
i did... he said it wasn't an std, but couldn't explain its sudden appearance either. i never had one on the head that i've seen so it worries me.
Bumps, blisters, rashes can be so many things and appear in so many different places. Most of the time they are non-STD related. best advice is to see a Dr for proper diagnosis.
