Hello for a couple of weeks now I have had

Patient: Hello for a couple of weeks now I have had some discomfort/irritation inside the tip of my penis. It does not burn when I go to the bathroom or leak. I have also had the feeling of a rug burn on top of the penis under the head where the skin wrinkles. There is no color to it and does not hurt if you touch it. I’m not sure if I have an infection of some sort or possibly kidney stones

Doctor:
