A few years ago I had a very bad fall off a horse which resulted in fractured sacral vertebrae. I was in a lot of pain, badly bruised and with irritated nerve from the fracture and impact which was sending tingling sensation into my thighs. My mum already had Arc4health so I borrowed her machine and used it daily for several hours. To my surprise all bruising and swelling was going down much faster than expected and pain was also getting better and better on a check up my orthopaedic doctor was very pleased with my speedy recovery.
