Such numbness of feet are common in alcoholics and metabolic disorders like diabetes, hypothyroidism, and
hypoparathyroidism. They can also be due to peripheral vascular disease, vitamin B12 deficiency or
malnutrition. Get your blood sugar and thyroid hormones levels evaluated. You can take some vit B12 for some
days and see if the numbness is gone or not. In case the symptoms persist then please consult a neurologist as
it can be due to some neurological disorder. I hope it helps. Take care.
