changes
* severe dizziness
* loss of coordination
* sudden severe headache
These symptoms may indicate a stroke.
## Can Nerves Heal?
Some nerves can recover, depending on what caused the damage and how severe it is.
For example, symptoms caused by:
* vitamin deficiency
* nerve compression
* medication toxicity
* poorly controlled diabetes
may improve when the underlying cause is corrected.
However, long-standing or severe nerve damage may not fully reverse.
That is one reason early evaluation matters.
## How to Protect Your Nerves
General habits that support nerve health include:
* managing blood sugar
* eating a balanced diet
* avoiding excessive alcohol
* not smoking
* staying physically active
* correcting confirmed nutrient deficiencies
* avoiding unnecessary high-dose supplements
* protecting hands and feet from injury
* following medical advice for chronic conditions
## Protect Your Feet if Sensation Is Reduced
If your feet are numb, inspect them regularly.
Look for:
* cuts
* blisters
* redness
* swelling
* burns
* pressure sores
Wear comfortable shoes and avoid walking barefoot
