PLEASE CAN MORE PEOPLE HELP ME??? MY HEAD SOMETIMES FEELS NUMB!!! I'm scared if it's dangerous!?

can anxiety be the cause. because i have anxiety. and i have frequent migraines. but i think migraines are hereditary in my family. but i'm scared sometimes my head seems numb. only half of it. i hope it's nothing serious. i'm really scared because i read about diseases that i think i might have.
