Do you feel the CIDP is a correct diagnosis? I there a definitive test for that?

I am curious since you mention most issues are in her hands.. and was wondering if all types of repetitive strain have been ruled out?
Specifically Thoracic outlet syndrome..
I suppose it could be possible to have both the CIDP and some sort of RSI ...
Can you describe the symptoms she has with her hands?
Any neck/shoulder tension, or forward head posture?
