There is a "muslce" right on my knee that randomly twitches, any idea why?

Question

It has gotten increasingly worse and it has been going on for about 2 weeks now. It happens a little above my actual knee and I am assuming it is a muscle, i don't know what else it would be. You can see it twitching by just looking at it. Any idea why? I'm 16 and 125 pounds if that helps.

Answer 1

Mine does the exact same thing.

Answer 2

Growing pains, your 16...Wait until you have heart palpitations...
