I use this red light belt to help with my sciatica and I've used it for various other aches and pains. I have no way of testing any results to be able to tell if this belt is aiding in the healing process or not, but It gets warm and it emits red light so I keep using it hoping that it's helping. With that being said, this belt is rather expensive so it had better be emitting the correct wavelengths and helping to heal what I'm using it for or I will have wasted my money. It's kind of like taking vitamins. If you're not sick, you can make the assumption that your vitamins are helping you stay healthy but there's really no way to know for sure.
I have chronic sciatica. I bought this belt to help me get over it. I’ve had lots of shots and been through physical therapy, but nothing has helped. I read about this and decided to give it a try. I’ll update my review after I use it for a while.
