I go between the two extremes.

At first thought it was due to my gall bladder surgery over ten years ago since some of the issues started then, until things came to a head last year. I was in major pain.
Had a CT scan, went to a gastro, had a couple of other tests - in the end all the could say was "hmmm." Put me on a couple of anti spasmatics for the digestive system, and some food suggestions. Helps with the pain, but not so much with the other stuff.
