Nisima, so sorry to hear you're having follow-on pain/injury! You're smart to be seeing a sports medicine orthopedist - they're really great at steering you onto a path to returning to activity as soon as possible.
As for other dance-related stuff you can do while immobilized, how about some of these ideas?
- Go through all the tapes and CD's you have, especially the ones you haven't listened to in a long time, and rediscover songs that you maybe didn't like back when you bought the music, but now they suit your taste.
- Write an article for one of the belly dance magazines on a pet subject - advice on what kind of dance floor to look for when renting a studio, how-to's in something you're good at, etc.
- Create some articles for your web site - could be advice, could be dance history/culture, could be how-to's, etc.
- Read one of the books related to belly dance that has been on your wish list a while.
- Work on a costume that you've been meaning to alter or finish.
- Watch favorite videos of performances.
In any event, I'm sending you my wishes for a speedy recovery!
