I am a women n my late 50 s, Having severe abdominal pain since 10:00 pm., Sunday evening. Stomach extended, gas, & belching. Passed some stool, then diarrhea this morning. No loss of appetite, no temperature. Painful to sit or walk. Tried Gas X, no relief. I have even tried a heat pack, no relief. Should I go to the ER? This has been going on for 2 days and I am miserable, hard to function.
