I suggest reading through
Complex Regional Pain Syndrome: Practical Diagnostic and Treatment Guidelines, 4th Edition.
In it you will find:
Quote:
Clinical diagnostic criteria for complex
regional pain syndrome
1) Continuing pain, which is disproportionate to any
inciting event
2) Must report at least one symptom in three of the four
following categories:
a) Sensory: Reports of hyperalgesia and/or allodynia
b) Vasomotor: Reports of temperature asymmetry and/or
skin color changes and/or skin color asymmetry
c)Sudomotor/Edema: Reports of edema and/or sweating
changes and/or sweating asymmetry
d)Motor/Trophic: Reports of decreased range of motion
and/or motor dysfunction (weakness, tremor, dystonia)
and/or trophic changes (hair, nail, skin)
3) Must display at least one sign* at time of evaluation in
two or more of the following categories
a)Sensory: Evidence of hyperalgesia (to pinprick) and/or
allodynia (to light touch and/or deep somatic pressure
and/or joint movement)
b)Vasomotor: Evidence of temperature asymmetry
and/or skin color changes and/or asymmetry
c)Sudomotor/Edema: Evidence of edema and/or
sweating changes and/or sweating asymmetry
d)Motor/Trophic: Evidence of decreased range of motion
and/or motor dysfunction (weakness, tremor, dystonia)
and/or trophic changes (hair, nail, skin)
4) There is no other diagnosis that better explains the
signs and symptoms
* A sign is counted only if it is observed at time of diagnosis

If you read through "Complex regional pain syndrome: are the IASP diagnostic criteria valid
and suf®ciently comprehensive?", you will discover that even those who meet all the criteria, especially early on, can get mis-diagnosed (either with CRPS or without).
The best thing you can do is prepare a list of questions for your doctor and make sure you get them all answered. good luck!
