[|Human|] FOR A FEW MONTHS I HAVE HAD A PAIN IN MY BACK RIGHT BELOW WHAT I CALL MY WING..SO BELOW MY BACK SHOLDER ALMOST TO MIDDLE..THE PAIN FEELS LIKE A NEEDLE AND ITS NOT CONSTANT BUT COMES AND GOES AND ONLY LASTS SHORT TIME. I NOW NOTICED SWELLING IN SPOT AND THAT SPOT ISNT HARD BUT SQUISY,SOFT LIKE A MUSCLE OR SKIN. WHAT COULD IT BE?
[|AI|]  Dear patient Pain in the middle of the back that comes and goes is colicky pain mist likely from renal stone. Colicky pain occurs due to muscle spasm in ureter during Stine passage. Do you have pain whole urination? Or past history of kidney stone? If yes than most likely cause of pain is renal click. Local swelling in back may be due to other reason. I would like to do ultrasound of PUB to confirm diagnosis. Please get it done from radiology center nearby you. Meanwhile, start tab Tuscan twice a day.  You need to consult urologist if report is abnormal.
