Ouch, that's a long time off too! My legs (feet/ankles especially) have always been my weak point, so I'm surprised my arm went first.
I'm planning to get some good lower body training in during my downtime. I'll admit I've gotten really slack at walking/running beyond whatever I get on the course, and by the middle of an average 18 hole course, I'm really dragging. That does nothing to help on tee shots, and I can see how I blew out my arm trying to compensate.
