Numbness

Have you ever slept funny and woken up with a numb arm? I woke up this morning with my right arm over my head, and I must have been pinching a vein or artery or something because my arm was completely numb from the elbow down. I'm talking no muscle control, completely limp. As the numbness started to fade I ended up with pins and needles down the entire length of my arm. Eventually full feeling came back and I'm happy to report that my arm feels fine. =)
