The night before last night I laid down on the floor and felt as if I had drank too much water. I then continued to go to bed, and once I laid down in bed, I noticed that my upper stomach (about and inch and a half above my bellybutton) was hurting. I then thought it might be indigestion, so I took tums. That didn t seem to help, and I couldn t fall asleep, so I took some advil, and that kind of helped. I was able to fall asleep. It did not wake me up at all in the night. I awoke to the same pain. This has lasted for almost two days now. This pain has also tended to move over to the right side of my stomach, just below my rib cage. I am wondering if this is appendicitis?
