@megroberts it does help some more than others. The problem is that you have to keep using it. It helps to bring good blood flow to improve healing and circulation. As a nurse, I used it many times for wound healing and neuropathy. It has been around a long time. Medicare actually paid for the therapy for wounds and neuropathy. I think the devices have improved a bit over the years. I can’t speak to pain relief with arthritic pain but it couldn’t hurt unless you are using it over undiagnosed conditions or lesions. People are purchasing the red light face masks for wrinkles etc. however, if you have undiagnosed skin cancer for example, you wouldn’t want to nurture it to grow. Like anything else, check with your doctor first.
