So I got this navel piercing about a year ago and it never fully healed. Sometimes it would be perfectly fine and look great but sometimes it would just start hurting and turn a little red and something that looked like "guts" would come out of the bottom and just stay there for about a week until it dried up and came off. After a while I got some scarring and the upper part of the piercing hole turned a dark brown color so I changed the ring so that the jewel was bigger and would cover the scarring. About 2 weeks later it got infected again so just today I took it out to clean it and oddly enough, it started bleeding and now I can't get it back in. The whole piercing is a little swollen and feels like it has a ball in the center. I don't know what to do and I don't know why this kept happening. Please help!
