<human>: I am having severe stomach pain that wraps around my lower back, so severe that it hurts to walk.  I have had an ultrasound and they found a shadow in my left kidney which led to me having a CT, the results of the CT came back last week and the results were clean.  I again started having severe pain in my lower abdomen yesterday wrapping around to my back and it hurts to walk.
<bot>: Hi, Since CT scan of abdomen is normal, and you still have pain in lower abdomen the possible causes can be as follows:Colitis. Typhlitis. Urinary tract infection. Enteritis. I would advise you the following in such a situation:Get stool and urine tested and if anything specific you can get it treated. Till then have symptomatic treatment with antispasmodic, analgesics and as needed. An opinion of a Gastroenterologist can help a lot. Hope I have answered your query. Let me know if I can assist you further.
