"   Question The problem that I write to you about is that I have numb fingers, especially the two middle fingers which turn a yellowish hue.  They can become completely frozen and this happens mostly when driving.  What could this be?   Answer Numbness of the middle two fingers does not fit neatly into any recognized syndrome. It is not compatible with carpal tunnel syndrome, which is common in women and people with arthritis, due to pressure on one of the nerves in the hand (the median nerve) from tightness in a fibrous sheath on the inside of the wrist. It is more likely that this localised numbness has a localised cause. Conditions which need to be excluded include synovial cysts, or ganglions, of the tendon sheaths. Another possibility is pressure on the nerves which run down the neck and into the fingers (brachial neuralgia). Have you had any whiplash injury or neck trouble now or in the past? This does not sound like a circulation problem. It is much more of a nerve disorder and only a thorough physical examination can pinpoint the exact source of the problem.  You mention that you are on various medications. The antibiotic, oxytetracycline and the oral contraceptive, Dianette, are not responsible for the symptoms.  The B12 isn&amp;#039;t responsible for the symptoms either. It is used to correct anaemia, which is due to lack of vitamin B12 rather than lack of iron. See your own GP for a thorough examination, so you can get this problem sorted out once and for all.
