I'm not sure if I have appendicitis or if something else is wrong with me. I am a 21 year old girl. I have been having stomach pains for the past couple of days it has kind of come and gone up until late last night. The only thing I have had to eat today were pretzels and not long after eating them I got sick. The pain isn't in my right side it is in the middle of my stomach. If I have appendicitis I don't want to wait until its to late to do something. Suggestions? If not appendicitis then what could it be? O and I originally thought it was gas I have taken gas x the past couple of days it didn't help also aspirin didn't help relieve the pain
