Thank you for your post. I am a firm believer in Red Light Therapy because it healed plantar fasciitis in my left heel after almost a year of pain, injection and doctor visits. I read about it in The Energy Blueprint and ordered the Red Rush model from Red Therapy and received a $100 discount using the code Energy Blueprint. I walk at least 3 miles every day first thing in the morning and have for years- it is my meditation and helps my degenerative disc in lower back so I was devastated when the plantar fasciitis became so painful I could no longer take my walks. Within a week of red light therapy I was back on the road and I would say within 3 weeks it was completely healed although I do use it occasionally to this day along with other parts of my body. I point the bottom of my feet to the machine 4-6” away for 10 minutes 5 days a week. Truly amazing and I am so thankful I found it. It comes with a hook you place on the wall to hang it, which you can raise or lower depending on whether you sit or stand. Or you can order it with a stand. If anyone is interested, I can post a picture. Thank you @kobe2026 for the great explanation. I am now using it for MGUS, hair loss (71 years old) degenerative disc and osteoporosis although I haven’t been as faithful lately as we are in the process of moving. I still use it 20 minutes per day focused on my feet, back and scalp. There are many great Redlight devices out there so I am not promoting the brand I chose but it sure works for me.
