Brief Answer: Detailed below. Detailed Answer: Hello! Thank you for the query. Lower right abdominal pain which gets worse when walking or standing a lot can be caused by inguinal hernia (even if there is no lump in the groin), inflammation of the adductor of the thigh, urinary tract infection/stones, ovaries inflammation or cyst. Inguinal hernia usually gives pain in the groin area. Lump can be present, but not necessarily. The pain aggravates when standing, coughing, lifting heavy objects. Please put your hand in the groin area while standing and try to cough few times. If you palpate protruding lump, hernia it is. Inflammation of the adductor of the thigh is a condition where due to physical activity (like bike riding, jogging), muscles get inflamed. The pain appears usually only when moving the leg (walking, standing). Urinary tract infection or stones can also give pain when walking, as the ureter is placed on the muscle in the abdominal cavity. You should have frequent urinating, burning while urinating with this condition. Ovaries issues can give strange bleeding, however pain can be the only symptom. I suggest you to visit your doctor, have physical examination and some tests done. Abdominal ultrasound, groin ultrasound, blood work, urine analysis should be done first. You should also consult gynecologist and have transvaginal ultrasound done. Hope this will help. Feel free to ask further questions. Regards.
