What causes recurrent back pain and frequent urination?
Patient: I have been experiencing back pain in the middle of my back and up between my shoulder blades for a few weeks.  I went to see my dr a week and a half ago and he prescribed an anti-inflammatory and a muscle relaxer to take once a day.  I'm still having back pain and now am experiencing frequent urination (at times dark and other times with little to no color). Why???? Doctor: You could be having a urinary infection. i suggest you get a urine analysis done, and if there are plenty of pus cells, may be even a urine culture and sensitivity as well. An ultrasound scan of your kidneys and bladder may also be of help if the pain is severe. you can try improving your water intake to flush out any infection, but most likely you will be required to take medication as well depending on the results of your tests.
