Desensitized

Went to a pain clinic & this guy told me to desensitize my face & retrain my nerves. He said if wind/cold bother me like they do then put my face in front of a fan. The idea of that sends major bad chills down my spine. He said to take a toothbrush & rub it on my face. To scratch my face over & over to desensitize it. I think he is crazy!!! I can't do that it would hurt too bad. He didn't give me any meds just that crazy info. Anyone else hear of this? If it was so simple I think every one would be doing this. Very disappointed. I just want to go outside again. I just want my life back.

That has got to be the craziest thing I have ever heard! Was this a doctor? I hope you are seeing seeing someone else soon!
Best regards
