Hi Allen,



This is what occurs in Peripheral vascular disease when there is permanent damage to the small vessels in the periphery. The skin becomes cyanosed and stays cyanosed as the vessels rarely improve their status.
As most of us with CRPS have TRANSIENT cyanosis accompanied often by a myriad of all clours of the rainbow then we do not have permanently plugged vessels as they do not have the capacity to suddenly unclog and get a blood supply.
The transient changes are a typical autonomic nerve response.
Some people with CRPS may also have peripheral vascular disease and thus permanent cyanosis and sometimes with worsening CRPS as vasoconstriction becomes more of an issue then cyanosis maybe there much of the time.

I have as severe CRPS as can be had, I have cyanosis sometimes but more often I am bright red and burning---a sign of vasodilation and not of clogged peripheral veins.

This is a highly discussed and often emotive topic but it must be continued to be discussed .
Cheers and hope you are doing OK
Tayla
