I have had a game changing result from using red light therapy for plantar fasciitis of the left foot. As someone who walks every day (100 miles per month), I was devastated when I developed plantar fasciitis and a heel spur and nothing seemed to help including injections. Was limping around for almost a year when I decided to order the Red Rush 400 from Red Therapy company after hearing about it from Energy Blueprint. At the time, the company (Red Therapy) was offering a refurbished model which I purchased with the discount code Energy Blueprint which saved $100. I believe I paid $400. After receiving it (it looked brand new and was probably a return as they offer a 60 day guarantee) I used it every day with the bottom of my feet pointed toward the device, 6” away for 10 minutes. Within a week I could feel the healing enough to walk a little outside again and within 2 weeks I was back to walking 3-4 miles every day. I continued to use the machine 5 days a week and also use it for other purposes. Recently, I pulled a muscle on the right side of my back which felt like a pinched nerve and would not go away for two weeks despite natural anti-inflammatory supplements. I hadn’t been using the machine for a couple weeks so one evening I used it with my back about 6 inches from the device for 10 minutes and to my HUGE surprise, my back no longer hurt when I woke up the next day! I did not expect that immediate result. I am a firm believer in this therapy for other issues as well that may take longer to see results. It has known benefits for thickening the skin (helpful for us 71 year olds!), arthritis etc. I looked on their website today and didn’t see that they are offering any refurbished models right now but the discount code Energy Blueprint still works. As a side note, you need to be undressed when using red light therapy as it does not penetrate clothing, and the distance from the machine depends on whether you need intense therapy or overall healing. If using on the face, remove makeup and sunscreen. Hope this helps!
