I am having pain in my large intestine above the left hip area around the point that the large intestine turns the corner into the Sigmoid colon. I have general pain continuously and more specific pain when I press my fingers into that area. I m not sure if I strained a muscle exercising or if it is a result of my wife giving me a cleanser consisting of raw oats, probiotics, walnuts, almonds, honey, and water. When I press the area with my fingers, I feel pain and the sensation of gas moving about. It just started last night and persists through today to the point I laid in bed all day. I began taking the cleanser yesterday morning and again this morning. Not sure if this has anything to do with it but I also took a protein drink with milk (8 oz.) after working out last night as my dinner. Any thoughts?
