I have diabetes (40 yrs) A1c 7.4,Left hand is swollen, when contracted into a fist the fingers below the first joint look white, no blood flow. unlike the right hand which has normal coloration when curled into a fist. Left hand has severe pain when attempting to make the fist. The pain is in the fingers, the palm of the hand and in the thumb.
