Every once in awhile, I get these small, single, water filled 'blisters' under my armpits. They aren't many, they don't itch or have redness or really cause any bother at all. I don't know if it is trapped sweat or something, and I can't find any information on the net about them. I am curious at to what they are. Maybe a deodorant/anti-perspiration thing?
The size is about that of a small pimple. I can get like 3 or 4 per armpit and underarm, they cause no problems, seem random in placement, and don't scar or anything.
Anybody have any clues?
Thanks!
