What ar signs symptoms of kidney stones and what can be done to minimize pain?

Pain, blood in urine. You might have no pain, but notice some gravel in your urine. You might have blood in your urine. If you do have pain, it usually comes and goes. It can be mild or very severe, and it can occur in your back, abdomen, or even in your testicles or labia. The pain can move as the kidney stone moves. Nsaids (ibuprofen or ketorolac) are good for the pain, or morphine if it is very severe.
Pain. Pain is the hallmark symptom of a urinary stone which is obstructing the flow of urine. Obstruction causes distension of the kidney and ureter, triggering a "visceral pain" response which can be severe and accompanied by sweating, nausea and vomiting. Other signs may be blood in the urine and fever if infection is present. Urgency/frequency can be associated with stone impaction near the bladder.
