You can buy these type of light therapy boots on Amazon. I went to chiropractor and got red light therapy boots, which I used 2x a day and electrostimulation, ultrasound treatment, hyperbaric oxygen treatment and supplements. Went 2x a week for 4 weeks. I saw no dif. I was allowed to keep the boots at end. Cost was $1500 for 4 weeks. It was supposed to be 8 week treatment for 3000 but they let me quit bc it wasn't helping. I still use boots sometime and they do feel warm but I see no improvement
