I have had a severe stomach ache on and off for the past 3 days, but tonight it s progressively worse. I have stomach tenderness to the touch, and the pain intensifies when I move, stand, or walk. The pain is located to the right lower side of my stoamch. I have tried using the restroom to see if that would help the pain and nothing happens. It also feels like I have gas pain, but I am unable to pass any gas. Should I be concerned?
