I have a strange dull ache pain (feels kind of like a bruise when pressed on) that's in the same place (if not slightly above) my belly button. About two weeks ago, I gave up eating gluten because I noticed that I was getting lots of severe gas pains after eating wheat-based foods like bread and crackers. Also recently I've put on some weight and my jeans are tight in the waist (right where the pain near my belly button is located). I was thinking that maybe I "bruised" my skin by wearing too tight jeans but there is no skin discoloration present. Then I started wondering if there was an organ in that area that could be the culprit. I would go to my doctor to get tested but I have lousy insurance which means I'd have to pay the cash price which I cannot afford at this point. Any ideas you might have would be appreciated. Thank you.
