I have a small bump above my belly button. Whenever I finish doing a set, it bulges out a bit. I can take my index finger and push it back in, only to come back out during the next set. It's not visible to the naked eye, and it doesn't hurt. It's also been like that for at least a couple of years, but I never thought much of it. Actually, the only reason I've been thinking about it the past few days is because I was reading something online about hernias, and I'm thinking that's what it is.
Have any of you guys had a hernia before? What were the symptoms? How serious is this? Is surgery the only way to fix it?
