@beachesanddreams Started with professional red light therapy at a Chiropractor's office who deals mainly with athletes using high technology. I found him on line when I had heard about RLT that was suggested to me by an orthopedic surgeon for my ankle repair. That place was booked out, so I called on this PT office. He also offered shock wave therapy and TECAR in addition to RLT. I then progressed to my arthritic hands/wrists and shoulders, all of which need surgery (Reverse shoulders and carpal tunnel, with complications- in addition to needing cervical surgery, but holding off an as much as possible as long as possible, already have bilateral hips and knees replacements now going on 15 and 22 years out. Not fun, so non-invasive was a great option. He has more powerful RLT, and between RLT and Shock Wave therapy, I found relief for my ankles, hands, wrists and shoulders. I was already being treated with Journavx and that has a limited treatment time- Since the professional therapy required thrice weekly meetings (short, but the drive, the cost, were getting a bit much - had about 20 sessions- and $4 g cost- so decided to order online. I purchased a $30 RLT in a strip I could wrap around my ankles, hands, neck, etc.. worked so well I bought another so I could use for two limbs at once. Then my daughter gifted me a larger panel one on a stand that can be adjusted in height and angle and I love it. I keep that upstairs and the small ones downstairs. There are several types of Light therapy, including Valeda Light Therapy for Age related macular Degeneration, which I am now going to investigate, due to a recent diagnosis. Hoping that will be as helpful. I hate to advertise but the large online store offers a ton of options- (I have not had success in finding them in small businesses), aside from RLT for cosmetic facial reasons. ) Hope this helps.
