2. It has been the experience of everybody that has actually kept track of it that tendon/joint injuries of a chronic nature just don't go away with a layoff. The first or second workout back after the layoff and the injury always shows up again, and it pretty much doesn't matter how long the layoff is. If the injury is acute, the layoff will probably work, but if not, she'll just have to learn for herself.
