light pain in my testicles. hello im 17 and Im feeling light pain in my testicles I do not have any lumps rashes or discharges or even fever altho I have a sore throat and my back feels a bit sore as if I had worked out of fell on it. I think its just a cold comming in anyways it kind of feels as it my scotum feels tight sometimes its because its getting cold but also sometimes its perfectly fine and my testicls have not retracted. my doctor says I will grow till 21 22 so maybe its just because im not done changeing also sometimes during masturbation my testicles go up to penis hight as if they were trying to get inside it goes right back after and I can even push them down.
