hi im seventeen and i noticed my testicles feel different, i don't know how they feel different i just know they do. also i'v been having back pain everyonce in a while even though i'v had a bad back for a while. also my testicles feel uncomfortable sometimes. does anyone know what this mite be, also my urine burns when i pee and white stuff comes out sometimes. could these have anything to do with each other because my urine burning has been on and off a good three months maybe four.
