You are very welcome. With kidney stones, they always measure the stone so it will be in your records. If you are still having pain, you still have the stone and it is the one in your uterer. You would not feel the one in your kidney.
The doctor explained to me the uterer is a very small tube and it spasm to move the stone along. That is where the pain comes from. If the stone was already in your bladder, you will be able to pass the stone because that opening is bigger than the uterer. You will not be feeling pain either. So it sounds like you still have the stone. If the doctor told you to take Advil instead of prescribing something stronger like Vicodin, it probably is a small stone.
But kudos to you for following up on it. Let us know how it goes. I hope you will be able to get this resolved soon. Darn those stones!
p.s. If you are able to retrieve the stone, get it to your doctor. They can test it to see what is causing the stones to form. Usually, once you make stones, you continue to make stones. They have methods to prevent future stones once they know how and why your body makes them.
If you ever wonder what labor pains feel like, that is pretty close.

Ha, ha!
