I had my first child in May 2014. I ended up getting a hernia above my belly button from pushing him out. I am very small built, only 5ft about 125lb but my stomach pokes a lot. I was told to not work out because it could cause it to burst. So I do light work outs to try to tighten my stomach but not strain on it too much, but I see no results at all. Is it because of my hernia? And will the removal of the hernia cause my stomach to go down a bit?
