What are you eating? Your body is not the one you had before and never will be. I had to have my sigmoid removed and a lot of my ileum in 2014. I had to find out what I could eat through trial and error. I basically started on "baby food" adding something new each week. If my body said that was good, no pain etc, I kept it on my "can have" list. Fiber foods had to go, beef was the first to go. Yes, hamburgers and all the good things I had on it had to go, forever. Having to have a balanced diet ment my new life style did not consists of the foods I once enjoyed. I now have foods my body finds that works for me. Fortunately I live by myself and don't have to fix two meals and smell the foods I once enjoyed that I can't have. When my body wasn't able to get the vitamins and minerals it needed because about a third of my GI track had been removed I started drinking a bottle of Boost a day. I first had it in the hospital and it works for me. I wouldn't recommend it until your bloodwork goes way down. It is expensive and not all stores sell it. As far as the pain the GI track is healing from the surgery and until it has healed expect pain. Doctors don't know how long it takes the body to heal from surgery, they only know what they can see. My first surgery took 20 years for me to have the same feeling again in my arm. Doctors have learned a lot in the last 60 years, they don't just cut. I have had laser surgery and I felt fine the same week. You may never be able to go to a friend's or family members home for a sit down dinner again, you and they will just have to accept it. If you do not take care of your body it may just get up and leave taking you with it. Good luck.
