2 years ago I very badly damaged my left elbow. Broken in 6 places and dislocated. Screws are holding it together. I have had to have constant treatment on it to keep it moving and the pain manageable. I have been wearing a snappy on that arm for 2 weeks now and I have noticed a large improvement in the flexibility and strength and it doesn’t seem to hurt as much. Soooo well done this is great for me.
