Again, good info. I had done some research about this because my husband gets these very badly from time to time. He's the type of guy who sweats profusely whenever he works at anything, but showers 3 times a day in hot weather so you'd think he'd be keeping bacteria at bay. His crop up on his inner thigh or buttocks or chest. Some have been rather large and really painful.
What I think is unusual is that his mother and sister also get these, sometimes at the bra line or on the groin. I found a type of condition that runs in families, which makes people more susceptible. Of course, right now I can't find the link...
His mother is diabetic, and his sister has another immune condition, but not sure why my husband gets them. And he's not shaving any of these areas.
His is more like a carbuncle, there is more than one. He will think he has one boil, it seems to get better and another pops up right beside it. I read that they are contagious, so good tip about the Barbasol.
If I find that link, I will post it.
