Testicular pain

Since the last 2 days, I have had not so severe pain in one testicle, usually when i move my leg (left). its pretty mild and visibly there's no difference so i doubt it's epididymitis, what do you guys think. (16M)

The pain is sometimes gone too, like if i sit for 2 hours then i walk it pains, but after i walk for 2 minutes it's gone for a bit. Sometimes it's barely noticeable (tingling) and sometimes it makes it uncomfortable to walk normally. I literally can't find any other disease that could cause this, so please help. I want to get rid of this problem before it becomes a big thing. i do not take any drugs or smoke whatever (im 16 lol) im in india and i just took a paracetamol yesterday.
