Please, have RSD / CRPS ruled out by a specialized doctor (Neurologist that treats these, not all do).

visit rsdsa.org for more reading info..

here's another,

Are you having any kind of pain, besides the itching? Burning, throbbing?

You needn't do anything drastic! Please, put that out of your mind.
Often, doctors aren't very good at a complex diagnoses, it took me 7 years, and over 100 doctors, and many many visits.

If you give us more information on your symptoms, and the general area where you live, someone here may know a good doctor for you.
In the meantime, any doctor you see, ASK TO RULE OUT RSD / CRPS!
Then, it becomes much more of a serious question for them! They'll have to take you seriously!

Wishing you the best,
Pete
