Hi,
Welcome to the ehealth forum and I am glad to help you out.
The various possibilities which present with such pain in the lower right abdomen are appendicitis, Crohnâs disease, bowel obstruction, ovarian cysts and pelvic inflammatory disease,irritable bowel syndrome , kidney obstruction or pyelonephritis, psoas abscess and volvolus (twisting of the sigmoid part of the large bowel on itself).
Investigations like ultrasound abdomen, CT abdomen and colonoscopy are required to confirm a diagnosis.My advise is to consult a physician and discuss these possibilities with him.
It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care.
