I was out at least 6-8 weeks after both my surgeries. I got infections in my incision, so had to do wet to dry packings all the time and that extended my recoveries by about 2 weeks. I would say 6 weeks is the norm. The thing to remember is you just had major surgery and it will take the most time to build your strength up. I would try to rest up as much as you can. Some folks have gone back in 4 weeks, but I personally think thats pushing it. By the way it took about 7-8 weeks for my incisions to close, but they had been fully reopened. I think yours should be a little shorter.
