Whats the name of this specific sleeping disorder?

Lately I have been having difficulty falling asleep. Everytime I attempt to fall asleep it feels like a shock, or as if bugs are crawling all over me. Im not really sure how I can decribe the feeling. But I usually slap my arms and try and make the feeling go away. This has been bothering me and can’t let it continue. At times Ill lay in bed awake for 5 hours before I even fall asleep, and im almost aways tired.
