I do understand how hard it is to find a specialist. But I would really recommend getting another opinion. Your symptoms really don't fit the crps diagnosis parameters. Check out this site

Wwwrsdhope.com
Www.mayoclinic.com -and search CRPS/RSD on their search'

It lists many symptoms. But you have to closely fit at least 3 symptoms. And that is only AFTER ruling any other conditions/syndromes out. There's is not a single test that can prove Crps, and even though early diagnosis can be key to recovery, should only be given when all else has been ruled out. It really comes down to a process of elimination, given a history of certain symptoms. Also it has 2 "types" Crps I- without a specific injury or trauma and Crps II- a defined injury or trauma. Either of those types can be the cold or warm crps. My left arm ranged from 8-12 degrees colder than my right for example. But it comes and goes and will present in patches or specific areas and sometimes will be the entire arm. Regardless you should print out the symptoms and diagnosis criteria and have your doctor go over it with you. I maybe he has a good reason for giving you the diagnosis he did, and you just need clarification!
