hello, i'm an 18 year old female, kind of overweight, and this morning i woke up with this strange abdominal discomfort. i took a gas-x and have since had 3 bowel movements. they've all been fairly small and kind of difficult. my abdomen feels bloated/under pressure and full, and there is some pain in my upper left abdomen, right under my rib cage, as well as above my navel when i press on it. nothing too terrible, just a vague sort of pain. i feel nauseous from time to time. i haven't had any crucial symptons such as blood in the stool or any sharp, stabbing pains, but i'm still kind of worried. i've never had this kind of thing before, and my grandmother died of colon cancer...so i'm kind of freaking out. any information would be really appreciated.
