Hi...I had some back upper back pain 3 months ago..kidney stone was found ( I've had them before) had the lithotripsy done but my urologist said that the stone was in the kidney and was not convinced that my pain was due to the stone. He was right because 1 week after the procedure I was on the er with horrible back pain along the entire bottom of my back and abdominal pain, bloating, and constant nasuea: they did a ct with contrast and can't find anything/ they did find blood in my stool: relased me to follow up with a gastro doc. He won't see me until next week and now I need a colonscopy
