I've had a problem for quite sometime now. It's not chronic, but I do experience it a few times a week. I get this pain which feels like it comes from my left kidney. Its not sharp, but it is really annoying. It typically doesn't last very long, and usually if I expell gas it goes away. So I have been thinking all along that its just gas pressing against something and not to worry about it, but I'm just kinda curious if it could be anything worse. I don't think it could be a kidney infection because my urine looks and smells fine. I drink water constantly and stay away from soft drinks and dark liquids that cause kidney stones, so I'm kinda confused. Does anyone have any ideas?
