Suggest Remedy For Pain And Discomfort In Testicle

HI, I was playing football the other day, and while I was playing my left testicle area started hurting! and for the next two hours it hurt while I was walking around and finally the pain subsided. But Its been 3 days now, and I feel much better! But sometimes when i walk i feel a slight discomfort near my left testicle. My left testicle is also hanging slightly lower than my right. Can you please advise me on this? thank you!
