Late night Saturday, I had a couple bowls of high fiber cereal. The next day I started having intense pelvic pain, gas both rectal & belching. When rectal gas, came some diarhea. This continued every couple of hours during that day. Abdominal gas pain continued. Burping continued, mostly after eating. By late yesterday, this condition seemed to lessen. Today, diarhea subsided, but gas pains continued. Especially felt pressure while walking. Seem to be much better than yesterday, but still continue to have the abdominal pressure or gas pain.
