Hi Rachy -- sorry about the pain, sounds frustrating.
Just wanted to say you might want to try getting a current pair or two stretched up AND across. Usually it's 24 hours per zone on the stretching machine but your shop's MMV.
Another idea, very low-tech, is to get to a dance supply store and buy a box of lambswool. I think drugstores sometimes sell these too. Then I'd probably wrap across all your toes vs just the big one to get the protection underneath/side/top. Ooh -- look, you don't have to do all that as some smart entrepreneur invented "pillows for pointe" http://www.discountdance.com/s.....fr=PILLOWS
Actually, do you need a consult with a podiatrist? Would it be better to be in rigid soles or super-cushioned ones?
