<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am a 53yr old woman. For the past 10days I have been having pain in my lower right side, going into my back. It hasn t subsided in any way. Waiting to have an ultrasound  <response>: Hello dear lower abdominal pain radiating to back, most common cause would be renal tract stones. Less likely to be from pathology of uterus and ovary. Hence its better to undergo ultrasound examination of abdomen and pelvis. If report comes in favor of renal tract stones, smaller stones do not require any special treatment. Bigger symptomatic need intervention. Hope this answer is helpful to you. Take care
