Hi,I am just about to turn 15.My right testicle hurts for 2-3 months,it's light pain that happens often.I did a self exam(it is a bit hard with a painful testicle) and noticed the tissue around the painful testicle is harder than around the normal testicle.It is very lightly swollen and only noticeable when touching it.The pain always occurs while touching or moving the testicle.It doesn't hurt when I ejaculate.
