Why does your lower right side stomach ache?

Answer 1

There are many causes and types of abdominal pain. The usual suspect for the lower right side is an inflamed appendix ( appendicitis ). The pain may also come from the intestines or muscles in that area. We are not good at isolating and pinpointing pain in that area, so we have to rely on a few other techniques. Some you can do yourself ( rebound tenderness, etc. ), and some have to be done with specialized techniques and equipment ( X-rays, etc. ).
