Different types of diabetic neuropathy show different symptoms, which can affect sensory, motor, and autonomic or involuntary nervous system functions.
Mild cases of diabetic neuropathy may go on for years and produce no symptoms. People with peripheral neuropathy that have symptoms may have some, or all, of the following:
- Pain and tingling in the arms, hands, fingers, legs, feet, and toes
- Numbness in the extremities
- Extreme sensitivity to touch
- Sharp pains, cramps
- Burning or stinging sensations
- Coordination and balance impairment
- Loss of reflexes
- Muscle weakness, especially in the ankles
Diabetic neuropathy might also cause deformities or problems in the foot, like hammertoe, arch collapse, or sores. The symptoms of pain, tingling, and numbness may get worse at night.
