I think I may have a kidney stone. My left side hurts where my kidney is at. Feels like someone punched me in the back and its bruised. A couple times there have been sharp pains that started from there and went around to my bladder. Having bladder pain now and I cant fully empty my bladder. Feels like a lot of pressure there. The pain in my back side where my kidney is at is a constant dull pain. Lower back and across the middle of my back hurts also so I am not sure if its just all back pain thats bothering me.View Thread
