Should You See a Doctor?
Arrange a medical evaluation if symptoms:
* persist for several weeks
* progressively worsen
* affect both feet or hands
* interfere with walking
* cause weakness
* disturb sleep regularly
* lead to repeated falls
* appear after starting a new medication
* occur with unexplained weight loss or other systemic symptoms
Early evaluation can sometimes identify a treatable cause before symptoms become more severe.
## What Tests Might Be Done?
Depending on the symptoms, a healthcare professional may consider:
* blood glucose or HbA1c
* vitamin B12
* thyroid tests
* kidney function
* liver function
* complete blood count
* medication review
* neurological examination
In some cases, nerve conduction studies or imaging may also be recommended.
## When Numbness Is an Emergency
Not all numbness is chronic nerve damage.
Seek emergency medical help if numbness or weakness appears **suddenly**, especially if it affects one side of the body.
Emergency warning signs include:
* facial drooping
* difficulty speaking
* sudden weakness
* sudden vision
