Health expert Dr Xand has issued a crucial warning to individuals who regularly experience pins and needles, advising them to seek medical advice promptly. During a recent appearance on BBC's Morning Live, Dr Xand discussed with hosts Gethin Jones and Helen Skelton the potential underlying causes of this common nerve sensation and when it should be a cause for concern.
Understanding Pins and Needles
Pins and needles, medically termed paresthesia, occur when nerves are compressed, such as from sitting in an awkward position for an extended period. This compression disrupts the nerve's ability to transmit clear signals to the brain, resulting in a tingling or numb sensation. Dr Xand explained that it can take several minutes for the nerve to stop sending these confused signals, which is what causes the uncomfortable feeling.
While occasional pins and needles are generally harmless, Dr Xand emphasised that persistent or frequent episodes should not be ignored. He stated, "If they last a long time, you should see a doctor. This is important because it could indicate problems with your nerves or other health issues."
Common Causes Requiring Medical Attention
Dr Xand outlined several potential causes of pins and needles that warrant a GP appointment. These include:
- Trapped nerves: Not just from temporary postures, but chronic compression in areas like the neck or spine.
- Poor diet and vitamin deficiencies: Particularly a lack of vitamin B12, which is essential for nerve function.
- Excessive alcohol intake: Long-term consumption can lead to nerve damage.
- Medications: Certain drugs may cause pins and needles as a side effect.
- Diabetes: High blood sugar levels can damage nerves, leading to diabetic polyneuropathy.
- Raynaud's syndrome: A condition affecting blood flow to extremities, causing nerve overactivity.
- Carpal tunnel syndrome: Compression of nerves in the wrist.
Vitamin B12 Deficiency: A Key Concern
Dr Xand highlighted vitamin B12 deficiency as a significant issue, especially for those on plant-based diets. He noted, "If you eat mostly a plant-based diet, very healthy, a great thing to do, but it's important to take a vitamin B12 supplement. If you're getting pins and needles, that may be a sign that you need to go and talk to your doctor, and not just buy a supplement."
The NHS supports this, stating that vitamin B12 and folate are vital for the nervous system. A deficiency can lead to symptoms like pins and needles, extreme tiredness, mouth ulcers, muscle weakness, and memory problems.
Diabetes and Nerve Damage
Regarding diabetes, Dr Xand explained that high blood sugar levels can damage the small blood vessels supplying nerves, leading to peripheral neuropathy. The NHS adds that up to one in four people with diabetes experience pain from nerve damage, with risks higher if blood sugar is poorly controlled, or if individuals smoke, drink excessively, and are over 40.
When to Seek Help
Dr Xand's message is clear: if pins and needles are frequent or persistent, it's essential to consult a healthcare professional. Early diagnosis can help manage underlying conditions like diabetes, vitamin deficiencies, or nerve disorders, preventing further complications.
He concluded by urging viewers not to dismiss this symptom, as it could be a warning sign of more serious health issues that require timely intervention.
