Raynaud's: There is a condition called raynaud's phenomenon, and it refers to a reduction of blood flow in the fingers and toes when the capillaries to those areas constrict. Usually that occurs in response to a cold stimulus, but can also be provoked by other factors. Raynaud's can occur by itself, or in conjunction with a connective tissue disease like rheumatoid arthritis or lupus.
