I had umbilical surgery repair several months ago. it reacurred about eight weeks after the surgery. my Dr did not use mesh. I told the Dr before my surgery to reinforce everything since my job can be laborsome and I am a weight lifter. I also had linguinal henia repair and he did use mesh. IT is still ok. I did not start working out till nine weeks and have been going very light since my understanding is it takes six months to totally heal. why would my Dr not use mesh to reinforce the umbilical surgery? I'm pretty sure it happened at work.
