Tingling can occur after temporary pressure on a nerve, but persistent or recurrent numbness may have many causes. The pattern of symptoms often gives important clues.
Details worth noticing
- Which fingers, toes or body area is affected?
- Is the sensation on one side or both sides?
- Is there burning, electric pain or weakness?
- Does it worsen at night or with certain positions?
- Is walking, grip or balance affected?
Possible causes
Nerve compression, neuropathy, vitamin deficiencies, diabetes, thyroid disorders, spine problems and some medicines are among the many possibilities. Diagnosis should be based on clinical assessment rather than symptoms alone.
When to arrange a consultation
Seek evaluation if symptoms persist, spread, recur frequently or are accompanied by weakness, balance problems or significant pain.
Urgent warning signs
Sudden numbness with facial droop, speech difficulty or one-sided weakness can be a stroke warning sign and needs emergency care.
Discuss your symptoms with a neurologist.
Bring your symptom timeline, current medicines and any previous reports to make your consultation more useful.
