Hellboy, you can make your own bed buddy if you want. Just take a tube sock, fill it with rice, and tie the end. It works great. After a certain amount of heating, the rice needs changed, it starts to smell. Kohl's also carry a great bed buddy..I have 2 of them, got them on sale for around $5-8. I keep one in the freezer and one for heating. I find sometimes cold feels as good as warm.
I find it amazing how different we all are, and yet some so much alike. My left shoulder is my worst pain area, and I also deal with sciatia, which isn't fun.
Getting By....do you ever find you have pain in your shoulders when you walk, like it doesn't matter how you stand it hurts? I try to walk everyday, weather permiting. I do not walk as far as I did last year, yet I walk every morning before breakfast.
