I waited to report this until I was sure.
I’m a runner who got Plantar 12 months ago from walking around barefoot all the time. Pain varied from moderate to stabbing pain, making it difficult to walk. I tried all the standard treatments: 3 kinds of night braces, 3 kinds of stretching, etc., etc. with no improvement – in fact they may have made it worse at times. Ice packs helped with pain but relief lasted only a few hours.
4 months ago I started using both an A9 on max for 2-4 hours per day and also a 1 watt low level laser for 3 minutes each on 3 spots. I am now 90-95% pain free and have resumed my running regimen for the first time in a year: 4 x 50 yard, full speed uphill sprints (high intensity training).
To be fair, I don’t know if it was the A9 or the laser (or both) that fixed the Plantar, but I was too impatient to do only one or the other and not running was driving me nuts during this wonderful COVID fiasco.
