I sneezed about a week ago and felt immediate intense pain in my left kidney. It almost felt like a cramp, but deep. Now if I flex my core, bowels, sneeze, cough ECT my left kidney is sore. If the action is uncontrolled, like sneeze or cough, it is excruciating. Sub nauseous but blurred vision and flash of sweat but subsides quicky. I have been drinking lots of water but haven t noticed any change in symptoms over the last six days. When comfortably resting there is no discomfort.
