Here are two more questions that I'm thinking about...
1.Do all stone passers have the urge to vomit (throw up)? I don't feel like throwing up even though my pain is so bad.
2.Do all stones pass thru the urethra? Dr thinks I passed stone, but I didn't feel anything in my urethra!

Hi - I responded to one of your posts below but to answer these questions - I have not always had nausea/vomiting with every stone I have had. As far as pain in the urethra, if the stone is small enough you may not feel anything when it passes out and unless you were straining your urine you would probably not even notice it.
