About four days ago I noticed a painful bump in my belly button. I cleaned it with alcohol and went on about my day later I noticed it had a head like a pimple and when I pulled the skin to look at it it poped. So I cleaned it again with alcohol. Thinking that since it poped it should go away but it still hasn't. It looks like a pimple but it keeps popping. I tried hydrogen peroxide last night and that seems to have gotten most of the pus out but it still poped again a little bit this morning. Has anyone else ever had this happen or know what it is and how to get rid of it?
