Urgent evaluation. If you haven't already had an urgent evaluation for this--please do at once!
Appendicitis. Pain in the right lower abdomen is appendicitis until proven otherwise. If the pain is severe you should be seen in the er or by your doctor right away. Once appendicitis has been ruled out then other possibilities can be considered.
