Hi MJ, if you are having severe abdominal pain you should go to the ER. Typically, appendicitis presents as pain in the belly-button region, then quickly progresses until it becomes very localized, severe pain in the lower right quadrant. There may be rebound tenderness, fever, vomiting - these are all red flags. I would call your doctor, at the very least, or go to the ER if it gets worse. Usually appendicitis will progress rapidly so if you feel worse and worse in a short time period, it's definitely time to go.
