I'm 26 years old, and since around 19, I've had these crazy weird muscle spasms that happen in my feet, and in my hands/arms. I have no clue why they've been happening for so long. What happens is, I'll start getting up to walk, or I'm just moving my feet in general, and sometimes(most of the time) once the spasm starts, my toes start to curl up, and my hand starts to curl up all weird, and my arm moves kinda whenever it wants to go.
