Actually i am a guy of 19 :) , In the past i mostly used to masturbate a lot but now these day i didn't coz i am a student and even a job holder but sometimes i get sick and have it. But now i have seen that on the left side of my testes it is quite bigger than the other, n even it pains sometimes drastically . Is this a big problem that i have to go for check ups and others or is there any minor homely treatment for it. I hope for the best result and medicine name from the concernes authority.
