I have spasms in my colon too, I have them sometimes on the right side, sometimes in the middle, and sometimes on the left, sometimes it feels like it goes to my back too. I did have pain as well, but not sharp pains. Dr put me on Levbid, and it helps a lot. Did you have any tests done like a barium enema, or even better, a colonoscopy?You really should get tested to rule out anything else.
