Hi Scott, I've just started using the H.E.M system after spraining my other ankle. So far so good, after 1 day the swelling has nearly gone and there is very little pain. constant stretching and movement of the joint has really helped speed up the process and working on the calf muscles has stopped any spasming or cramping. I took a chance on your book and I'm glad I did, it is helping a lot and is easy to follow. Many thanks!
