Sir, Since may be one year or more I am feeling numbness in feet, toe fingers cold, lack of sensation in toes, dark patches below knee joint, skin getting hardened, if scratched bleed. I am 55, vegetarian, weight, 87 kgs, vision normal. By habit I avoid sweets and potatoes, kindly advise what to do, for info, I need to inform you that I consume costly alcohol daily, in recent past for 2 years I have stopped walking.
