When I had a back injury, I tried so many different products to help relieve the pain. I tried a Bed Buddy, and it ended up helping me bring the most relief. It helped restore some movement in my back so I could perform the rehabilitative exercises, strength exercises, and stretching I needed to do so I could speed up the recovery process. Effectiveness I felt it worked pretty well in helping to relieve my pain. It worked better than any gel pack I had. Ease of Use It is very easy to use. You microwave it and apply it to the area of pain.
