I'm sorry you're not feeling well. You should definitely call your surgeon's office to check in and see what they say. However, at only 11 days out, it's still VERY early. At that point, a lot of us felt weak, had major problems trying to drink, couldn't eat at all, couldn't hit the protein targets, couldn't walk much. It wasn't until week 3 that I started to feel better. I know on this forum you see a lot of people post that they had no pain and were able to go back to work after a week. I believe them and I'm glad for them, but not everyone has that experience. It's normal to feel pain and weakness after major surgery. But if you're at all concerned, that's what your surgical team is for. I called several times when something happened that I didn't expect and they were always willing to listen and advise. Yours should be too.
