One thing that I find very useful here on the mountain is my homemade heating pads. They have a duel purpose really because you can heat them up in the microwave or you can put them in the freezer for a cold pack. They are really simple and quick to make and are a lot cheaper than store bought heating pads too!
I have a couple different sizes for here on the mountain. I have a small one to lay across my head for headaches and a larger one for bigger aches and pains. ( they work great for ladies monthly pain)
Just cut two pieces of cloth in the size and shape that you want your pad and sew together. Leave an inch or so open so you can add your filler. I like to use white rice. Fill the opening about 1/2 - 3/4 full. You don't want it to be really full- you want it to kind of mold to your body.
Sew the opening shut - and it is ready to go!!
