Can't see the pic... but I very familar with Kidney Stones.
I've passed about 15 of them... most without knowing there were there until they hit the water.
There were another 2 that they had "to go get"... and we'll leave it at that.
Probably the most painful experience of my life (phyiscally) so far... and hopefully ever.
I forget what exactly mine were made of... it was Calcium something or other. They told me to cut back on Calcium (at that time I was consuming lots of milk/cheese/etc) and the colas/teas.
Here's to hopeing thats your only one. :beer:
