It might be a tic. I have stress ticks where my neck stiffens and then I throw my head to the side. It’s my not my only motor tic but it’s the most distressing of them all. I’d tell someone although I’m sure you’re not dying, just under a lot of stress or possibly have early Tourette’s. Lots of love, take it easy <3

Maybe your mom drop u on head when you were a baby

It's not a headache, like my head literally jerks or move suddenly idk its hard to explain

Headache is the most annoying thing ever seen
