<s>[INST] Hi, I am Jessica. I have been experiencing sever low back hip pain for a week. It s getting worsse. Hard to walk. My neuro called yesterday with my blood results. Eerything was good, but high potassium. I went to y family doc tyoday, and was told i Have a bladder infection? Sounds to me more like kidney stones?? [/INST] helloThanks for query .Severe low back pain without any positive neurological findings is most likely to be due to presence of stone either in kidney or Ureter.Please consult qualified Urologist for clinical and digital rectal examination and get following basic tests done to confirm the diagnosis.1) Urine routine and culture.2) Ultrasound scanning of abdomen and pelvis3) Serum electrolytes Further treatment will depend upon result of these tests and final diagnosis.Dr.Patil. . </s>
