I am just about to go mad !The shockwave I had last week was to make the kidney to break up in small pieces,well yesterday a piece to big to go through the tube,got stuck,in the tube!!!!!!!!!!!!!! I had to go back to the ER and get it flushed out,causeing untold pain!!!!!!!!!!!! Thank god, my Dr was on duty he had me shot up right away with a very strong drug!In my belly! right above the tube,pain was gone in minutes! The other 4 1/2 was blood work ,x-rays.When I go back to the kidney DR,I am going to tell him no more shockwave ,cut it out ,I cannot have this pain and tube going on for months!
