I hate to be so graphic and personal but I've had that happen to me so many times I went to my doctor. Turns out because of my MS I get constipated ALOT and the twist of the instestine is right under the area where the left lower rib cage is. It was painful and it would go away after awhile but I never put the 2 and 2 together. I took Zelnorm for awhile but it didn't help so now I do fiber mix stuff every day.

I hope yours isn't anyhing serious. If it keeps up I'd say go to your doc.:angel:
