Hi, I'm 13 and have been getting a burning pain in my penis when urinating and sometimes just when doing nothing. When I pee I only manage to get a small amount of urine out so I take quite a while to do so and have to go regularly. Also when I pee the head of the penis kind of swells up. Any idea what this is and whether I should get it checked out by a doctor? Any advice would be greatly appreciated and ask for more information if needed.
Thanks
