[/INST] Hello and thank you for your question. If it is your appendix, you would most likely have rebound pain, basically what that means is that if you push on the area of pain it hurts worse when you quickly let go and let your stomach bounce back to normal.  If you are having this pain I would recommend going to the ER.  Stomach pain on the lower right side can be caused by a multitude of things.  Best best would be to go to your doctor and be evaluated for ovarian cysts, appendicitis, irritable bowel syndrome, crohns, gall stones, kidney stones. Best wishes and good health Dr. Ward </s>
