My 12 year old son has been having LRQ pain on and off since July (4 episodes). Usually the pain comes on suddenly and resolves in several hours. Last Sunday, he has another episode but this time, the pain is constant. Everytime he has an episode, he experiences nausea, vomiting, and severe pain that will not go away with meds or changing positions. We are now in our 9th day with normal test results and scans but still having pain and he is losing weight due to lack of appetite. Doctor discovered that he has a retrocecal appendix. Could it be appendicitis?
