Fina homebrew, using glutes and quads. only problem is in my glutes.. have a pinkish, slightly raised area on both cheeks about 1.5" in diameter roughly, as well as lumps under the skin. Anyone think this may be just reaction with the BA? I'm not certain it's an infection because it's not sore at all, and it's not like my entire ass has swollen (I've been reading the other threads of infection on this board) I haven't had any problems with my quads - I switch every day, so I only hit the same muscle once every 4 days. it's been like this for only the last 4 days or so...If it is an infection, I know obviously the way to go is the ER, but would using Ampicillan or injectable Penicillan now work? Thanks from a newbie..
