Passed a kidney stone?!
Question: Passed a kidney stone?
Answers:
It is definitely possible. Depending on the size of the stone you may be able to pass it without any problem. Pain only occurs with a kidney stone when it blocks the flow of urine from the kidney to the bladder. You should be drinking enough every day so that you urinate about two liters. It does not matter what you drink as long as you are not drinking a lot of one thing.

It could happen.
BUT if you really did pass a kidney stone you would not "think" that you did it, you would most definitely know because it is painful. A irregular shaped something passing through a skinny tube in your body would hurt like hell!
See a doctor and find out what it was, if it was a stone... there could be more and tests could prove that. If it wasn't a stone then you'll be on the path to find out what it is.
