Goodluck to you and your friend. I only know about PEMF and will read about sOMF. I bought an ICES-PEMF a few years ago just to try it out for my back pain and it did help in reducing it and healing it. It's small and battery operated and was designed as a wearable but you need to come up with your own way of holding it close to your body. https://www.youtube.com/watch?v=ZnGpibdAoic
