i had a kidney stone a few weeks ago, had surgery, had stent in and the stent was just removed a few days ago. i have been in severe pain ever since, especially in the bladder. i have to urinate constantly (at least every 10 minutes), where i only go a few drops, and then the pain is even more worse. its almost unbearable. flomax, percocets, nothing is working. is there something wrong? what should i do about this?
