<s>[INST] last night I had severe pain in my right side mid abdomen. It hurt while using restroom and continued while I walked to my bed. It was painful to walk and to try to stand straight. It lasted about 3-5 minutes then I was able to get back into bed. Today I have dull pain in the same area. Slight body ache, headache, and slight nausea. [/INST] Hi. Thanks for your query. You have got a classical history of pain due to a stone in the mid-ureter. Your history of sudden pain while going for restroom and then a dull ache indicates the stone in the ureter. I would advise you to have urgent ultrasonography, Urine tests : Routine, microscopy, culture and sensitivity. Once the diagnosis is made you can have treatment as per the situation which can be a lithography, ureteroscopy or open surgery </s>
