I'm a 52 year old woman in excellent health except for this problem that began Aug. 2004 after vacation in Mexico. It started with an ache in my left side below rib cage & change in bowel movements. I am frequently constipated, crampy in lower abdomen, sore in up
per abdomen & every bm has a lot of mucus
. In the last 3 months, the condition worsened & now I have excessive gas, bloating & 3-6 bm's per day, usually within 15-30 minutes after eating.
