I blew out a stomach muscle and it took my belly button with it. I lived with it for years, it never hurt as much as my back, so no big deal, until it got to be to much. I had a world class awarded surgeon. he told me no tobacco, it can cause the surgery to not heal. He gave me rush Limbaughs favorite dope for pain, and took them away after i took one because he did not like how I reacted to them and told me to get back on my all natural supplements. I will never have a six pack, the most I can do is a 5 packy mound of what I have left of my torn up abdomen muscles, but I was in Canada on a canoe trip six weeks after the surgery. I did absolutely nothing to risk pulling the stitches apart until then. Luckily mine has not returned, i have heard of local cases done by local surgeons that have had more than one repeat surgery, because things were not done right to begin with, of course it was always blamed on the patients. This is nothing to mess with, go beyond careful. You do not want to have them do it again.
