Hello, So during my last period I developed a bump on my butt(closer to the anus but not in or on it but nearby). This is the first time this has happened to me and it was very painful almost like a zit with pus in it, I popped it (or so I thought) and the swelling went down but the pain continued. It stayed for the whole time I was on my period and I continued to use baby wipes to clean the annoying zit after I d use the bathroom. What could the zit be? And do you think it ll return?
