What is going on with my legs bouncing on its own?

It’s a muscle spasm. It happens in legs a lot, mostly from the calf to the thigh areas. It can also happen pretty much anywhere on the body with a lot of muscle.

its kinda like a eye twitch i agree with Emily its something going with ur nerves this might go away on its own but if it doesnt i consider youh going to see a doctor

mine only do it when i sit still for too long.

It happens to everybody and it is just the problem of muscles. But it happens very frequently and you get irritated by that, it is better to consult a doctor as within limit, everything is bad

sounds like it could POSSIBLY be a condition known as restless leg syndrome, which is worse tahn the normal bit of leg movement that most people experience- if i focus on it i can get my leg to start shaking for a while. as stated above- consult your physician to get a better diagnosis of what is- OR IS NOT happening.

You are putting your leg in an awkward - but balanced - position and it will just bounce on its own. No harm in that. If it bothers you (my Mother used to tell me to stop it and I didn’t even realize I was doing it) simply shift your foot either more under your chair or so your heel is on the floor and it will immediately stop.

Might be a twitch, a nerve or something?
