2.Im 13 years old - 4-5 Months ago my right ball was to much biger than my left ball,and then after 2-3 weeks the ball was reduced to much,it was only a little bigger than my left and it's still like this,and then i started reading those things and i freaked out,i guess im sick and if anyone can tell me something about this please tell me :)
Thats normal i think XD
