"neuropathic pain" is concluded when the type of pain or symptoms described are known to be neuropathic. RSD/CRPS type 1 - has yet to be found to have identifiable "nerve lesions" that would then classify it with that etiology.

I don't think the medical community is trying to say that the symptoms aren't neuropathic in nature and progression. Instead they are saying RSD/CRPS causes neuropathic pain symtoms/progression but the exact cause/trigger is still unknown.
