4) Foot Pain and Numbness
Medically known as diabetic neuropathy, this particular sign develops over time when high blood glucose levels start damaging nerves throughout the body. Although all nerves of the body are affected, it primarily targets remote nerves in the extremities such as those in fingers of the hands and feet. Some diabetic people may not experience any symptoms of the nerve damage, many others may notice pain, numbness, or tingling sensations in the extremities. Diabetic neuropathy initially develops in the feet and then progress upward as the disease advances.
