I am about 6 weeks out of the hospital from having a kidney infection and a stint placed for my left kidney which stayed in for aprx 3 weeks. I had the stint removed 2 weeks ago. Presently when I lay down and roll onto my right side it feels like my left kidney drops and it also feels like someone is applying intense pressure on my left side causing pain and when I roll back onto my left side it feels like my kidney moves back into place and the pressure is relieved, but it leaves a dull aching pain on my left side.
