Anyone have experience dealing with IBS lower left side ache that stays with me all waking hours? This is a very familiar pain. I have had two colonoscopy's in the last 20 years. Diagnosed with severe spasms of the sigmoid colon. Kind of a thorn in the side thing. When I was young I described it as a "phantom pain", not very specific but a general ache. Recent bout has lasted for a couple of months now. After a while it causes a state of phycological depression and weariness. Very difficult to maintain concentration and patience. Anyone had any luck managing this type of chronic pain? It's hard to believe that the colon can be spasming every day, all waking hours! I am having a hard time understanding what my body is doing.
