Hi i have diagnosed with kifney stone measuring 6.8mm but it reduced to 5.4mm to the latest ultrasound scan.

And pain i can referred as stinging pain. Im taking homeopathic remedy for stone. He used to say when sand comes in baldder it irritate all of the urinary tract. But now why i have pain in testicles and back.
