I believe it is very common to still feel c/s scar pain. Burning, aching, twinges. I still do and it's almost 2 years.

I have/had adhesions. Internal and as a result of endo. They can cause incredible pain and (in my case) had twisted around my bowel and made digestion sometimes very uncomfortable.

I would think the two things are unrelated, but seeing a dr would be the best first step.
