Tests & diagnosis
Treatment & management
- Treating the underlying cause, such as controlling diabetes or replacing B12
- Medicines specifically for nerve pain

Frequently asked questions
Can nerve damage be reversed?
Sometimes. If caught early and the cause is treated — for example correcting a B12 deficiency or controlling blood sugar — nerves can recover. Longstanding damage may be permanent but manageable.
Why does it affect the feet first?
The longest nerves, which reach the feet, are usually affected earliest, which is why numbness and tingling often start in the toes and move upward.
