Oops, I did it again

I sprained my ankle again, this time injuring the Achilles tendon where it attaches to the bone in the heel. I know, I know. Only I could sprain the same ankle twice in a two week span and injure it differently each time... It's a special talent I have, and it's taken me my whole life to date to perfect it. My doctor tells me that when you tear ligaments that it kills some of the nerves (in the ligament one must assume), so while you may recover strength in an injured joint you need to retrain the remaining nerves to react faster to prevent re-injury. Or something like that. He mentioned balancing on a medicine ball or balance board as ways to retrain these nerves. Sounds like just one more thing I'm gonna have to shell out cash for. But not until the cast comes off...
