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.
Step 1: Materials
1 Pair of Socks (make sure there are no synthetic materials in socks!)
1 1/2 cups of Rice
Step 2: Making the 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.
Step 3: Using the Heating Pad
Put the heating pad in the microwave for 1-2 minutes. Makes sure to keep an eye on it so it doesn't smoke.
You will be surprised how long It will retain the heat.
Place under your neck and lay down. Don't watch t.v., use your computer, or do anything that will strain your neck while using the heating pad.
