6. 8mm Stone in Right Proximal Ureter.

I had excruciating right abdomen and back pain. I went to a nearby clinic who told me to get an ultrasound since it doesn't feel like appendicitis. Ultrasound revealed a 6.8mm calculus in the right proximal ureter + mild hydronephrosis on the right side. The doctor gave me some syrup and told me to wait for it to pass through urine. But my life is a living hell. Pain shoots up every 3-4 hours and NSAIDs don't cut it. I am taking Tramadol + NSAID to get relief but even they don't last for more than 3 hours. Every 3 hours, the pain comes back again and it's worse this time. 1) What should I do - Should I ask for Lithotripsy instead of waiting for normal passage? Because I read it's difficult to pass 6.8mm sized stone. 2) Also, how long will this renal colic pain last? It's been a day and still it keeps coming back. I can't bear the pain anymore. 3) Will it stop after a day or will it continue till the stone is out? PLEASE HELP ME OUT.
