My hands are almost always cold. I'm cold a lot when the air conditioning is on, even when no one else seems to be. My legs cramp up if I sit with my legs crossed, and the leg on top will get pins a needles pretty quickly. I wake up a few times through out the night because my sleeping postion has made either a hand or arm fall asleep so much it hurts.

What can I do, if anything, to fix this? It drives me crazy to feel like I'm not comfortable and I'm always cold.
