“Tingly feet" can be a sign of nerve loss. The nerves in the feet come from the lower back. Pressure or chemical change in the nerve can cause a tingling sensation in the feet. Any sensation that is out of the ordinary can be an early sign of neurologic or vascular problems. In addition to tingling, feet may feel numb or feel like they are "falling asleep." There may also be a burning sensation in the feet.
Diabetes is one of the most common medical conditions with which "tingly feet" can be associated. A thorough evaluation by a foot and ankle surgeon is advised to determine the cause of "tingly feet."
