Pain months after kidney removal

I am just over 12 months post kidney cancer surgery. I was diagnosed following sudden pain and hemorrhage and was rushed into hospital needing embolisation after which both kidney and tumor were removed. Prior to this I had no health problems and suffered no pain. After surgery I had bad back pain that was dismissed at the time, I changed consultants and hospital due to poor after care. Since then the pain has persisted and is now accompanied by some right abdominal pain. I take gabapentin pain relief daily but there is no firm diagnosis of why the pain persists other than possible nerve damage. My GP has been excellent.

Is there anyone else suffering similar following nephrectomy?
