my left side (front/back/side) started bothering me mid december and I had to go to the ER for extreme pain in my side on New years, since then I've had a urologist appt where they took two samples because my primary suggested it may be kidney stones. The CT scan in the ER and the ultrasound at the urologist didn't find anything. So they tested the samples, both of which tested negative for kidney stones and kidney infection. I've been drinking tons of liquids and have noticed that since new years there have been these black specklike things that are hard to see unless I reflect light off the toilet water. They aren't hard like gravel and infact feel more like lint. I honestly have no clue what could be wrong with me because I don't have any urgency to pee and my side still has annoying twinges even though I've been urinating these for months now.
Any suggestions as to what it could be?
