Hello dear user! I have gone through your query and understood your concerns! Thank you for sharing them on healthcaremagic. Generally numbness inf fingers with cold feeling, pale/white fingers and nails, may indicate a condition called Raynaud syndrome which comes from small blood vessels strictures. Smoking is a factor which may worsen this condition. Cold intolerance may be seen in thyroid gland diseases with hypothyroidism too. I would recommend you to go through some tests and examinations to determine the real cause of your concerns. - Blood sugar and lipids - Thyroid hormones - Complete blood count and electrolytes - Blood pressure monitoring. According to the findings we will be able to have a more accurate opinion about your health. Talk with your family doctor at your healthcare center and let him know the results of the tests. I hope this answer was helpful to you! Please kindly rate it as helpful and write a short review about your experience with me! I would appreciate that a lot. Thank you and best regards! DR ERIOL.
