bottled ballerina....what a great name!

if you can't swim, maybe you could try aqua therapy classes and just stay off the bad leg. One interesting class I took, they gave us floating vests and we all jumped in the deep end and did exercises while kind of hanging there in the vests.....we "ran" in place, did all kinds of leg exercises. You could just go easy on the bad leg. You could also just get your own vest and use the pool at whatever local public pools or gyms/clubs are near you.
Good luck....let us know what worked for you.
