Hello. I Had Shock Wave Lithotripsy On Tuesday. I Have

Hello. I had shock wave lithotripsy on Tuesday. I have had severe pain in right kidney that seems to fluctuate. I went to the hospital the night of the procedure because of the kidney pain and the sent me hom with Valium, Percocet and zofran. I stopped taking the Percocet yesterday because I thought it was binding me up and making me constipated. Now I have severe stomach pain that won't go away I've tried several enemas with not much luck. I am very bloated and in tremendous pain. I don't know what to do. Should I try another laxative or is that causing the pain, I'm thinking about just getting back in the Percocet and deal with the constipation with oral laxatives. Thanks for your input.
