This was posted a few months ago but are you talking about your fingers going white and numb? Toes also? I get that and I have fibro.. it is called Raynauds syndrome. It is not a symptom of fibro.. it is a separate problem and it can be in conjunction with other illnesses or a stand alone syndrome.

Changes in Skin Colour and Sensation

Once the attack begins, a person may experience three phases of skin colour changes (white, blue, and red) in the fingers or toes. The order of the changes of colour is not the same for all people, and not everyone has all three colors. Pallor (whiteness) may occur in response to spasm of the arterioles and the resulting collapse of the digital arteries. Cyanosis (blueness) may appear because the fingers or toes are not getting enough oxygen-rich blood. The fingers or toes may also feel cold and numb. Finally, as the arterioles dilate (relax) and blood returns to the digits, rubor (redness) may occur. As the attack ends, throbbing and tingling may occur in the fingers and toes. An attack can last from less than a minute to several hours.

my doc says i dont have raynauds but i do have fibro, but i have numb fingers....and a slight color change but my fingers have been numb for months now and some slight weakness in the hand...i also have low iron(which he says aint the prob) and maybe he thinks its a vitamin d prob! and wants to give me 50,000 iu's of vitamin d in one day (enough to od you) i dont wanna do that! i have an apt for a neurologist...but i dont think thats it

any ideas?

its a possibility you should try taking vitamin d it wont hurt you.

Yip, I have it too. Don't waste your money on othe tests. I'ts defnitely a sign of fibro. Sometimes it goes into my arms as well. Do you have pain when you press on your finger joints? Mine is terribly sore!
