I "earned" my umbilical hernia going for extra reps I shouldn't have on the ab wheel.
Now I have to use a belt on rows, squats, deads, stifflegs that exceed 275lbs. Standing military press bothers me the worst--anything over 135lbs unbelted is excruciating. With the belt I don't feel it at all.
Mine originally stuck out a bit, but has since receded. I can still push it in a bit if I press it, but I feel like some of the tear must have healed on its own (although not completely). I was very careful after I noticed it and made sure not to do anything that aggravated it.
Since then I've deadlifted 550lbs and haven't had a problem. Like I said, strapping up with the belt seems to prevent the pain and further protrusion.
At this time I cannot afford the surgery (poor, in college) but plan to get it as the extra money comes in. I don't want to have to worry about it anymore.
