Had kidney stone surgery Friday and had my stent removed after 4 days. For 36 hours since the burning during urination has been real bad and the bladder spasms for the 5-15-30 minutes after have been unbearable. How much longer can I expect that razor blade feeling to last and would flomax, Ditropan, and the iodine pill be a good way to eliminate the pain? And how long until I should be worried
