I think I might have appendicitis. My stomach has been hurting for about 25 Hours (since the night before), and it is slowly getting worse. I assumed it was indigestion, since I have been having digestion problems for about a week, so I didn't eat any food all day (over 18 hours) and nothing has changed, if not more discomfort. I have been noticing an unusual amount of unination also, is it possible that i have appendicitis?
