I often strain my neck after staring at a computer for many hours. A couple weeks ago I strained my neck really bad and couldn't go into work for a couple days. Jason gave me the idea to make an at home heating pad.

Tie a knot at the top of the sock.
Put the sock with the rice in the other sock, knot side first.
Tie end of outside sock.
