<s>[INST] I have a sporadic pain, lower left side about belt-level. Passing gas relieves it for a while. I should point out that we are in the process of moving, and that I did strain myself several days ago. I am 57, male and had a diverticulitis several years ago. This pain is nowhere near as bad, much lower and toward the front. [/INST] Hi. With a history of diverticulitis and pain that is relieved by passing gas, I suspect the pain originates from your bowel - it can be some obstruction with gaseous distension of the bowel, and passing wind will make it feel better. My advice is go for a checkup and Xrays will be able to pick up distension, fecal loading or a mass in the abdomen. Your doctor will be able to manage further.Hope that helps. </s>
