CHRONIC STOMACH AND BACK PAIN

I have been suffering with severe stomach and back pain for the last 4 months following a number of major stomach operations. I am waiting to see the surgeon again , due to the pain I am in. I am taking tramadol 4 times a day, but am sruggling with bending walking and standing for any period of time.
I had a sigmoid collectomy in October 2009 and further open surgery in November 2010 for a tripple hernia.
I also suffered with a ruptured appendix many years ago

I am concerned about having any more surgery as I think this will just compound the issue. Is there anything else that can be done or is it likely I will suffer with this pain for good. I am trying gentle exercise and watching my diet.

I would appreciate your thoughts.
