Ugh! I'm so tired of having doctors say that there is no pain when the stones are in the kidneys!! I finally found a primary as well as an ER doctor that both confirmed there may be pain even if the stones are not passing.
If I were you I'd definitely seek out a urologist and get their opinion. Also, knowing the exact sizes would be helpful to you, as anything larger than about 4mm may not pass on its own. It's unlikely that the stones will dissolve, way more likely that they will pass (eventually...)
I've been waiting 3 months, had a failed lithotripsy, and now have 2 new stones as well as watching the others continue to grow slowly. Definitely get to a urologist as soon as you can so they can check them out!
The stones could be at the boundary between the kidney and the ureter. There are many strange ways pain could be triggered. They're unlikely to dissolve. If you have insurance, you should just see a urologist and have them remove the stones and have it over with.
Oh and they did not tell me how big they were, but the discharge paper work said 1-6mm
