I get huge bumps on my thighs/vagina. I ve always thought they were boils or infected hairs. They get large, sore, and drained by themselves within a week or two. I got another one today except this one was so sore I couldn t lay right. I looked at it and there s a large area around the bump that looks swollen as well. I finally got it to where it would drain but what s coming out of it is very oil like. Should I be considered? What are they? How to I keep from getting them?
