Hello, 1. As the pain is on the right side, ask for ultrasonography of HBR [hepatobiliary region] for amoebic liver abscess and cholecystitis. Pain could be a pleural pathology. [ask for a chest x-ray to exclude pleuritis, pleural effusion] 2. Since most of the investigations are normal, thus take an opinion of gastroenterologist or medicine specialist who might ask for an investigation like endoscopy, gastric analysis, colonoscopy At present all I can say that it might be a gastrointestinal symptoms thus you should contact either a general surgeon, gastroenterologist or gynecologist and if not sure consult your general physician who after reviewing your case history and physical examination will refer you to specialist concerned. 3. The most common diagnoses of lower abdominal pain relate to uterine, gonadal, renal, and bladder complications, [less common causes like primary dermatologic and musculoskeletal problems as well as referred pain and neuropathies related to underlying vertebral and spinal cord complications can also occur], so examination is mandatory for further workup and management. In Females, [before colonoscopy], consult a gynecologist for any underlying pathologies like endometriosis, uterine fibroids or pelvic inflammatory disease [PID]. If after pelvic examination, the doctor suspects an underlying condition, she may order further investigations like MRI, CT, hysteroscopy, laparoscopy since surgery may be needed to remove the abnormal tissue [if any]. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Munish Sood
