Nothing.

KUB (stands for kidney, ureters, bladder) x-ray = nothing. (yes, x-ray not CT Scan. Cystine stones don't show on x-rays -_-) Blood test = nothing (yay!) Ultrasound = one tiny stone on the left. My pain is on the right, so nothing.

That's great, but I'm still in effing pain in one spot.

At least my kidneys are fine.
