The infrared heating pad is the best investment I have made in regards to pain relief. I have suffered from neck and back injuries for over 10 years. I have several bulging discs, bone spurs, stenosis and arthritis in both my neck and lower back. The many combinations of medications and various injections were the only sources of relief I had until I purchased the heating pad from the Healthy Back Institute. I have owned several heating pads throughout the years and while the heat helped ease the pain, the effects were short-lived. The relief I get from this heating pad lasts for hours. I am able to move around much easier and perform the normal household work like vacuuming and mopping that I was told to avoid. Every morning before work and every evening after work, I spend 1/2 hour to an hour on the heating pad and get immediate relief from my lower back pain and then I use it on my neck and shoulders at the end of the day to relieve the tension built up from working on a computer all day. I am so pleased with this product and have recommended it to many of my friends. Thanks to it, I am able to be more active and have a better quality of life. Peace Love Light ~ Tammy Krauss
