Pain in abdominal / stomach area feels like a heavy full up feeling ive been feeling it for 4 days what is it?

Abdominal Pain: Are your symptoms increasing in frequency, duration, or severity? If not, you may continue to watch before seeking medical attention. However, if it is associated with diminished appetite, nausea/vomiting, change in bowel habits, fever, weakness, you should seek medical advice. Otherwise, you can try taking some OTC Pepcid (famotidine) Complete for a couple of days and see if it goes away.
