thenar cyanosis

yesterday morning i was driving to tennis... my wrists hurt a little... naturally i looked at them for something positive... omg... my thenars were blue (thenar = the prominent piece of meat under your thumb)... they're literally blue and cold... i've never seen more obvious peripheral cyanosis... for 2 seconds i was worried that they will necrose off... um.. i need to rescue them... so i rubbed the 2 thenar against each other hoping to improve circulation... nope, still bluish... next, i blew some warm air over the thenar areas... because my big mouth's not big enough to cover the whole thenar area... only the part covered turned red... good... it's reversible... o vasoconstriction... for half a second i wonder if it's raynaud's of the thenar... o come on, carry on driving... hee...
