After brachytherapy, my penis burned like during urination like I was peeing jalapeno sauce with pins and needles. At first, I thought the pH difference between blood (in urine) and normal urine was the cause. After the blood cleared from my urine, I still felt the burning-pins-and-needles pain during urination. But then I realized, what is the difference in the urinary tract from bladder to penis? Why does the pain only happen in my penis and not between the base of the penis and the bladder? The difference is TEMPERATURE. The urinary tract temperature is at or close to core body temperature from the base of the penis to the bladder. Obviously, the penis temperature is lower because it is external to the body. Pain Relief, YES!!! is to put ice cubes in a zip lock baggy and put the ice bag below your penis during urination. The urethra /urinary path is located at the bottom of the penis. For those with urinary flow problems, this may be a balancing act between urine flow and cold pain relief, since the cold can constrict the urethra in the penis. If the flow stops, take the ice bag off, reapply the ice bag when flow starts back up.View Thread
