Patty,
When I have KS pain, I feel like I'm being kicked by a horse or taking kidney punches from a boxer.
On the 2nd day of the KC, I had the kicking sensation...I was pained & got a small fever.
I layed down..the next morning I had a small stream & then a surge! It was a large stone.
I have passed some good sized stones before, the small ones don't hurt & the larger ones you just cry & bear it!
Always talk to your physician if you do feel you have kidney stones, they can get an X-ray to evaluate how many & their placement.
I had a very large (17x19mm) stone that completely blocked off my Left Ureter, if I'd had tried a cleanse, it would have done me more harm than good.
Standing by!
