That means you have a very large kidney stone (calculus) that is slowing the flow of urine. Personally I would not wait 2 weeks to see the doctor.
haidinfo,
From what you've said, your doctor is saying that you have a small kidney stone and I'd bet that he/she is figuring that the stone will pass on it's own by the time of your appointment in two weeks. That's why you were given Flo Max as a medication in order to help it pass, hopefully. A stone as small as yours can still hurt but should pass pretty easily on it's own. Please let us know how you are doing
