Your appendix (or however hell you spell it) probably needs to come out. if the pain is constant and never leaves go to doctor or ER.
Welcome to the gastroenterology community! It is probably not your appendix because of the location of the pain. The appendix is located much lower than that. However, I would recommend seeing your doctor about this. Good luck.
Many people have right upper quadrant pain that can be associated with stomach issues, gallbladder issues or problems that result from discomfort with a portion of the ascending colon/transverse colon.
