My mom got me a LightRelief product for Christmas. She got one for herself. After 30 days, we both agreed that it does help. It uses Red & Blue LEDs on a flexible silicone rubber pad that can be positioned anywhere on the body. It has an optional switch to turn on the Infrared LED. If it gets too hot, you can switch off the Infrared. It uses Long Wave Infrared, not conduction heat from a heating pad. I can position it over inflammed sinuses, earaches, thymus gland and on any sore muscle it feels better. It has a built-in timer that shuts off after 15 minutes and can be loaded up with rechargeable batteries for portability. Cost is $80 for one and $40 for an extra one. It also has straps for attaching to the body so you don't have to hold it in place. I would recommend it to those of us who can't afford an infrared sauna.
