** Thanks for contacting with your health concern 1. As I m unable to examine you directly and because symptoms are acute in origin, thus I m of the following opinion: . At present all I can say is that it might be a gastrointestinal symptom thus you should contact a general surgeon [to exclude appendicitis], PS. 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, consult a Gynecologist for any underlying pathologies like endometriosis, uterine fibroids or pelvic inflammatory disease [PID] 2. 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].
