Lower back pain while sitting/ standing and better when standing?
Patient: I was diagnosed with a uti yesterday and was given a shot and I am taking antibiotic which today is the last day of the medicine.  But I have been having low back pain when I sit or get I get up from a chair I am more comfortable standing up the pain in my lower back feels like something is pulling Doctor: I think along with UTI either you are having a renal stone or back muscle spasm. Both these disease causes such type of pain as you have mentioned. So now i would advice you to get ultrasound of your abdomen and X ray of your spine. These two investigation give us clear picture about your disease. If it turns out to be back sprain than take muscle relaxant like myoril and myospaz. If It is renal stone than  meet a urologist.
