I have not been to Switzerland, had my treatment in Paris. If you look under 'needle aponeurotomy' on this forum you will find one of your fellow countrymen, Colin, from Brisbane who has left his email address. Perhaps you could start by emailing him.

George Rappoport is an excellent physician and performed NA on me during June 2001 with wonderful results.

Other noted physicians had informed me that my hand was too far gone for NA, but Georges did the trick.
