<s>[INST] 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? [/INST] Here you have symptoms of pain in stomach from two days daily in night. The cause of this could be related to indigestion, acidity, or it can also be due to kidney stone as well appendicitis. I suggest visiting a doctor if it does not improve with anti acid and change with food habits and timing by keeping it proper as well healthy. Here doctor will ask you for ultrasound of abdomen after proper examination and I suggest going ahead for it for proper diagnosis and plan treatment as per that. Also keep your food habit regular and healthy. Have fruits also in diet. Keep doing daily morning and evening walking for 15-20 minutes. Do not have heavy dinner and keep dinner before 8:00pm daily. I have given here general guideline since the examination is not dine by me, but I am sure this will be useful if you follow it. Take care. </s>
