I have exactly the same as you!
There was a huge investigation for many years I even had the blue dye injected into my spine for the MRI, I was on a mountain of pain medication which caused me to have too have good part of my stomach removed. A friend I had at the time... ( who has since died of pancreatic cancer

)
Her daughter was actually in theatre at the time of my operation, she said she couldn't believe how much was removed.
I then had too deal with irritable bowle disease, which still flares up on occasions if I'm not careful.
Due to all of the above I lost my faith, especially in the medication. I found it only worsened my body by increasing my pain in addition causing even more problems
I have to live with PAIN because pain killer's wear off after a while.
Luckily I had a good honest G.P at that time that explained a lot of this too me.
From there on in, when my trusted G.P was no longer around, I went on my own discovery, I cut out the pain killers and stomach meds, then found a more natural way, for instance, without the sweeteners and colourings for my stomach. I take husks on occasions
For the first time since all that I've started taking glucosamine msm & chondroitin. My dog is now taking this to. It's taking the edge off along with the turmeric.
I'll never walk straight I never have and I'll always have pain. But i prefer to go my own way and cope the best I can while searching for various exercises.
The amount of pain medication I had through that was well over the limit, thankfully I didn't become an addict.
My thoughts are with you and I hope you find your answers
