I was beyond skeptical. Read about laser therapy in a book recently and figured hey what the heck. I am training for my first Ironman and have flair ups of plantar fasciitis in my right heel. I have done everything else -- the split, compression, manipulation, trigger points, stretching, etc. etc. and it's all good and helped but this blew my mind! Within one week of three 1 min treatments three times a day I felt about a 75% reduction in pain and am now almost pain free! I even recommended to my PT. Maybe I only BELIEVE it works so it's working... but whatever. It allows me to run so I use it.
