incisional hernia?

Well I was feeling pretty good yesterday and was out in the garage messing around and trying to get a bolt out and apparently pulled to hard on the wrench and I felt something funny.
so I came in and uncovered the incision to find a large egg like bump right at thebottom and along the side of the incision. I called the wls program nurse and explained to her what was up and she said that as long as I was not in pain and I was having bms that I could wait to see the surgeron on monday. I go monday to have staples out so I will see what he thinks. I have been wearing my girdle and it seems to help make the egg smaller there is very little pain sort of like an anoying toothache. I hope that I didn't screw something so that I would need additional surgrey but I will see. Anybody else do something stupid like this or something similar.

Thanks

Bill
