Random upper body spasms and neck twitches

Throughout my life I'd have random muscle spasms in which I assumed were normal, it happened rarely and I didn't think much of it, but for some reason early last month I noticed it happened a lot more often, at least 3-5 or even more times a week it'll happen, I've never been tested for any disorders but I don't want to assume I have any as I would consider myself a pretty healthy person.

My upper body tends to spaz/twitch and when it does it's like I'm trying to shake something off of me although there's nothing there.

My neck tends to twitch to the side or downwards.

I never feel any pain when this happens as well.

I'm 15, Male, Around 155-157, and I weight about 55.5kg, I don't take any medications, never smoked and I don't think I've had any medical issues
