Just read that.... venous pooling in the hands (showing as bulging/distended veins) can result from impaired sympathetic vasoconstriction. Seems to argue AGAINST an over-active sympathetic nervous system or some variant of CRPS.
Nonetheless, I have had 5+ doctors suggest this...and refuse to do any other vascular diagnostics.

If there is someone out there who does have CRPS and this symptom of bulging/distended veins in the hands, along w/ very painful hands, I would really appreciate hearing from you, and learning more. Right now...having a hard time being convinced....
