Why You Have Numbness And Tingling In The Hands And Feet

Have you ever felt that odd sensation of pins and needles in your hands or feet after sitting in one position for too long? This familiar feeling can often be shrugged off as your limb “falling asleep,” but when this sensation becomes a regular occurrence, it might be a signal from your body that something more serious is underway.

So, what exactly causes these bizarre feelings of numbness and tingling? Let’s take a closer look.

1. Vitamin Deficiencies

You might not realize it, but lacking certain vitamins can lead to numbness and tingling. Vitamins B12, B6, and E play crucial roles in nerve health. When your levels dip, your nerves rebel, causing uncomfortable sensations. So, consider checking your vitamin levels; a simple supplement might just do the trick.

2. Nerve Compression

If you’re feeling that weird numbness, it could be from nerve compression. Common culprits like carpal tunnel syndrome in the wrist or sciatica due to a pinched nerve in your spine can lead you to experience these sensations. Sometimes, a little physical therapy or adjusting your posture can help ease the pressure.

3. Diabetes

If you’ve got numbness or tingling, diabetes could be a contributor. High blood sugar levels can lead to nerve damage, known as diabetic neuropathy. This type of damage is sneaky and progressive, so you might not notice it until it becomes more severe.

4. Alcohol Use

Yes, your evening drinks could be to blame. Excessive alcohol use can lead to nerve damage, a condition termed alcoholic neuropathy. Reducing alcohol intake can help mitigate these effects and improve nerve health.

5. Kidney Disease

Did you know? Kidney issues can cause toxins to build up in your body, affecting nerve function and leading to numbness. Regular check-ups are vital, especially if you have other symptoms like swelling or changes in urination.

6. Hypothyroidism

An underactive thyroid might be slowing things down, including your nerve function. Hypothyroidism can lead to swelling that compresses nerves, causing a tingling feeling. A simple blood test can tell if your thyroid is to blame.

7. Infections

Certain infections, like Lyme disease or shingles, can attack your nerves directly or cause inflammation that leads to numbness and tingling. If you’re also experiencing fever, rash, or other peculiar symptoms, seek medical attention.

8. Autoimmune Diseases

Autoimmune conditions like multiple sclerosis (MS), rheumatoid arthritis, or lupus can impact your nerves or the blood vessels that support them, leading to tingling sensations. These diseases can be complex, so professional evaluation is crucial.

9. Medications

Think about what’s in your medicine cabinet. Some drugs, especially those used for chemotherapy or to treat HIV, can cause neuropathy as a side effect. If you suspect your medication, a discussion with your healthcare provider could be enlightening.

10. Poor Blood Circulation

Poor circulation can leave your extremities feeling numb. Conditions like peripheral artery disease (PAD) decrease blood flow to your limbs, making them feel cool and numb. Staying active and managing your blood pressure can help improve circulation.

11. Toxic Exposure

Exposure to heavy metals like lead or mercury can be disastrous for nerve health. If you’re in an environment with potential toxic exposure, protective measures and regular screenings are essential for maintaining health.

12. Pregnancy

During pregnancy, swelling and fluid retention can compress nerves, particularly in your legs, causing tingling sensations. These usually resolve after childbirth, but it’s always good to discuss any concerns with your healthcare provider.

13. Stress and Anxiety

Believe it or not, stress and anxiety can physically manifest as numbness and tingling. Managing stress through techniques like meditation, exercise, or therapy can help alleviate these symptoms.

14. Aging

As you age, the risk of conditions that affect nerve health increases. Regular check-ups can help catch and manage issues before they lead to symptoms like numbness.

15. Idiopathic Causes

Sometimes, despite all investigations, the cause remains unknown—a condition doctors might call idiopathic neuropathy. Even so, managing symptoms and maintaining a healthy lifestyle are beneficial.

16. Peripheral Neuropathy

Peripheral neuropathy isn’t just one condition but a group of symptoms caused by damage to your peripheral nerves. It’s common in those who have had injuries, infections, or exposure to toxins. Symptoms include troubling numbness and tingling in the hands and feet.

17. Stroke

A stroke interrupts or reduces the supply of blood to your brain, which deprives your nervous system of nutrients and oxygen. If you experience sudden numbness and tingling, particularly if it’s on one side of your body, seek medical attention immediately—it could be a stroke.

18. Heart Attack

Similar to a stroke, a heart attack can cause peripheral numbness and tingling, especially if it affects the oxygen supply to parts of your body. It’s a less common symptom, but it’s crucial to be aware of it.

Frequently Asked Questions

What can I do at home to alleviate numbness and tingling?

Regular exercise, maintaining a balanced diet, and ensuring you get enough vitamins, especially B and E, can help. If symptoms persist, consult a healthcare professional.

When should I see a doctor about my numbness and tingling?

If the numbness or tingling worsens, spreads, or is accompanied by pain, weakness, or coordination problems, it’s time to see a doctor. Also, consult a professional if it appears suddenly or only on one side of your body.

Can numbness and tingling be prevented?

To an extent, yes. Managing underlying health conditions like diabetes, avoiding excessive alcohol, protecting yourself from toxins, and maintaining a healthy lifestyle can all help prevent neuropathic symptoms.
