Appendicitis. Evaluating abdominal pain is like solving a mystery. There are usually many different possibilities, which can be narrowed down by asking the right questions, doing a careful examination, performing simple blood tests+/- radiology tests. Constant rlq abdominal pain needs to be approached as "appendicitis until proven otherwise" due to the risks of no treatment. Please see a doctor asap.
