One third of lupus patients exhibit an unusual sign, referred to
as Raynaud's phenomenon, in which fingers tirn red, white &
blue in response to stress or cold.
It may be observed in the fingers, feet, tip of the nose & outsides
of the ears.
There are many other causes of Raynaud's, & it
can be seen in most other rheumatic autoimmune diseases, & also
on its own.
Medications can be prescribed that increase the flow
of the blood to the hands.
Preventative measures should be taken, such as wearing
gloves, avoiding cold environments, not smoking, & using hand
warmers.
