The other day it appeared to have a couple of insect bites. A few days later, they became firm and A bit bigger, I was told that they were boils. There was one on my waist and four under my belly button. The one on my waist popped and was fine but for some reason when I went to pop the ones under my belly button, they wouldn t pop, they would just get bigger. After applying a hot rag and squeezing it, a small amount of puss came out but it seems as if they all connected. What could this be?
