@turkay1-- Do you have diabetes?
Diabetes doesn't directly cause numbness and tingling but neuropathy, or damage to the nervous system can. This occurs after years of living with diabetes. Abnormally high blood sugar levels start to damage the vascular system leading to circulation problems. This is why diabetes has to be well controlled.
Feet and leg numbness and tingling may occur from poor blood circulation. Diabetics have to be very careful about these symptoms and seek treatment. If left untreated, diabetic neuropathy can even result in amputations.
