might be sore is this possible?

last week i examined myself for testicular cancer. Things went good i'm fine but i think i checked myself a little to hard not on the testicle itself but the tubes connected to it. is it possible to check yourself a little to hard. i checked myself more than once because it became sore and i think i did it a little to hard each time. the soreness feel came right after i checked so if i wouldn't have checked myself i wouldn't have this problem. it goes away and comes back most of the time if i forget about it feels fine. it doesnt hurt it just feels weird. how can i make it unsore just wait, ice it, what. how long good the soreness last. please dont tell me to go to the doctor because i want to c if it goes away naturally i still can run, workout, play sports just fine.(Im 16, if u want to talk about just leave ur email or IM in ur answer) Thanks!
