Pain in both upper left abdomen under ribcage and lower right abdomen just beneath belly button. Feels like a knawing sensation and at times fluttery like spams..my stomach has been bloated and I have a canker sore in my lower lip on the gum line. My bowel movements have been normalish...basically no diarrhea or constipation ..and having a bowel movement does not help nor worsen my stomach pains...Prior to the symptoms I mentioned above, I was having upper right sided knawing burning pain, but I attributed that mainly to fatty foods I had been eating recently. I ve also been on cephalexin for 3 weeks for an infection I was dealing with, which I had to stop the other day due to these stomach symptoms worsening. Please help!
