However, because it seems like my calves are forever tight (I had problems with shin splints early on), I asked if tightness in my calf could cause problems in my ankle and he said yes--tight calf muscles can restrict ankle mobility(!) so that's also a big possibility (yay relevé!) Time to break out all my self massage tools and see if that helps.
And maybe one of these fancy calf stretching deals:
(They had me use one during my PT recovery for my knee injury a few years ago and it was the best thing ever).
In any event, whatever this is seems to be pointe related. I've come to this conclusion because during the winter I was dancing a TON (in HEELS) and had no problems whatsoever, but now that we're back to our normal dance schedule I'm back to doing pointe more regularly (though its only 1 hr once a week), and the stinker is bugging me again. GRUMBLE. I just can't win with the whole pointe thing, can I?
