Numbness & Tingling
Diabetes can affect your feet by damaging nerves in the legs and feet. This condition is called peripheral sensory neuropathy, or diabetic neuropathy.
Peripheral sensory neuropathy, characterised by a loss of nerve fibres, first affects the nerves furthest away from the trunk, for example, in the toes and the soles of the foot. This condition reduces the speed of conduction of impulses along the nerve, and as a result, the function of the nerve is impaired. Peripheral sensory neuropathy usually presents symmetrically, and affects the sensation of the feet.
Common symptoms are:
- Pain in the feet (may be sharp, tingling, or burning, particularly on the soles of the foot, toes, or front of the legs).
- Skin tenderness.
