Almost everyone has felt pins and needles after sitting cross-legged too long. That brief feeling is harmless. But tingling, burning or numbness that keeps coming back, or never quite goes away, is your body asking for attention.
Common causes
- Blood sugar problems. Diabetes and pre-diabetes are among the most common causes of nerve symptoms in the feet.
- Vitamin deficiencies, especially vitamin B12. The risk is higher with age, a vegetarian diet or some medications, such as metformin.
- Nerve compression, for example sciatica from the lower back or carpal tunnel at the wrist.
- Alcohol, some medications and chemotherapy, which can all affect nerves.
- Thyroid, kidney and autoimmune conditions.
Red flags: get help right away
Seek urgent care for sudden numbness or weakness, especially on one side of the body; numbness with confusion or trouble speaking; loss of bladder or bowel control; or a foot wound that won't heal.
Preparing for your appointment
Write down when the symptoms started, where you feel them, what makes them better or worse, and every medication and supplement you take. Your doctor may order blood tests for blood sugar, B12 and thyroid function, and possibly nerve conduction studies.
Where supplements fit
A supplement such as Arialief can be part of a daily routine, but it isn't a substitute for a diagnosis. Once you know what's behind your symptoms, ask your doctor whether a supplement is appropriate. Bring the label details with you.
