I just had brachytherapy surgery this morning. Everything seems to be fine except the extreme burning (like razor blades) when I urinate. I hope this goes away soon or at least lessens. I also have a bruising (discoloration) on the lower bottom of the head of my penis. I will call my urologist tomorrow and tell him. Reading past comments, I understand that the "burning razor blades" is not that uncommon with some after brachytherapy surgery. I also had blood in my urine but that seems to be dissipating now. My biggest concern was a sore scrotum from all those needles but I feel nothing in that area. At least I'm lucky there. Has anyone else experienced this extreme burning like razor blades sensation while urinating after their brachytherapy surgery?
