Why Do You Feel Tingling and Numbness in Your Hands and Feet?

That Familiar "Pins and Needles" Feeling

We've all experienced it — you sit cross-legged for too long and your foot goes numb. But what happens when the tingling and numbness shows up without any obvious reason? That's your body sending you a signal, and it's worth paying attention to.

What Actually Causes Tingling and Numbness?

The tingling sensation, medically called **paresthesia**, occurs when a nerve is compressed, irritated, or damaged. Think of your nerves like electrical wires — when there's interference in the signal, you get that buzzing, prickling feeling.

Common Reasons You Might Experience This

1. Nerve Compression

Sitting or sleeping in one position for too long can press on a nerve. This is the most harmless cause and usually goes away once you move.

2. Carpal Tunnel Syndrome

If your hands and fingers frequently tingle, especially at night, you might have carpal tunnel syndrome. The median nerve in your wrist gets compressed, often from repetitive tasks like typing or using a phone.

3. Cervical or Lumbar Issues

A herniated disc or spondylosis in your neck can send tingling down your arms. Similarly, lower back issues can cause numbness shooting down to your feet.

4. Peripheral Neuropathy

This is common in people with diabetes. High blood sugar over time damages the small nerves in your extremities, leading to persistent tingling, numbness, or even burning pain in the feet.

5. Vitamin Deficiencies

Low levels of Vitamin B12, B6, or D can affect your nerve health. This is more common than people think, especially in vegetarian diets.

6. Poor Blood Circulation

Conditions that reduce blood flow — like peripheral artery disease — can cause numbness, particularly in the legs and feet.

When Should You Worry?

See a doctor if the tingling is persistent (lasts more than a few days), gets worse over time, is accompanied by weakness or difficulty gripping objects, or affects one side of your body suddenly (this could indicate a stroke).

How Physiotherapy Helps

A physiotherapist can identify the root cause through nerve mobilization tests, postural assessments, and strength evaluations. Treatments may include nerve gliding exercises, manual therapy, postural correction, and targeted strengthening programs.

Don't ignore what your body is telling you. Early intervention can prevent a minor nerve issue from becoming a chronic problem.
