Causes of Numbness in Feet and Face

Causes of Numbness in the Soles of Feet and Face

Experiencing numbness or a loss of sensation in areas like the soles of the feet or face can be alarming. But while conditions like multiple sclerosis can sometimes contribute to numbness, there are many other potential causes that should be explored.

In this comprehensive guide, well discuss the various reasons you may be experiencing numbness in the soles of the feet or face and steps you can take to find relief.

What Causes Numbness in the Soles of the Feet?

Numbness or decreased sensation in the soles of the feet has several possible explanations:

Peripheral Neuropathy

Damage to the peripheral nerves that run from the feet up to the spinal cord can cause neuropathy. Contributing factors include diabetes, alcoholism, infections, autoimmune diseases, and nutritional deficiencies.

Tarsal Tunnel Syndrome

When the tibial nerve gets compressed as it passes through the tarsal tunnel in the ankle, it can lead to numbness or pain in the soles of the feet. Causes include overuse, arthritis, sprains, bunions, and cysts.

Sciatica

Irritation or compression of the sciatic nerve as it travels from the lower back down the leg can cause numbness in the soles. Common causes are herniated discs, spinal stenosis, and pregnancy.

Vitamin B12 Deficiency

Lack of vitamin B12 can contribute to nerve damage and neuropathy. Vegans, vegetarians, and those with absorption disorders may be at risk for B12 deficiency.

Hypothyroidism

An underactive thyroid can slow nerve conduction, potentially leading to numbness in the extremities like feet.

Raynauds Phenomenon

This condition causes blood vessel spasms that restrict circulation to the hands and feet when exposed to cold. Numbness results from diminished blood flow.

Multiple Sclerosis

MS can damage the insulating myelin sheath around nerves, producing numbness or tingling in the feet. It often affects both sides of the body.

If youre experiencing unexplained foot numbness, see your doctor for an evaluation to determine the underlying cause.

What Causes Numbness in the Face?

Some potential explanations for numbness or decreased sensation in the face include:

Bells Palsy

This condition causes temporary paralysis or weakness on one side of the face. Its caused by inflammation of the facial nerve and results in numbness.

Trigeminal Neuralgia

This painful nerve disorder affects the trigeminal nerve supplying sensation to the face. Numbness or tingling may occur alongside intense facial pain.

Multiple Sclerosis

Facial numbness or odd sensations can occur with MS, since it damages nerve fibers throughout the body and brain.

Stroke

A stroke affecting the brains sensory cortex can cause numbness or tingling on one side of the face or body.

Head Trauma

Injuries to the head and neck can potentially damage or compress nerves that bring sensation to the face.

Dental Problems

Issues like impacted wisdom teeth, infections, or nerve damage from procedures may cause face numbness.

See a doctor promptly if you experience sudden or unexplained facial numbness that may signal a neurological issue requiring prompt treatment.

Diagnosing the Cause of Numbness

To get to the root cause of numbness in the feet or face, your doctor will likely perform:

• Medical history and physical exam
• Neurological evaluation of nerve function
• Blood tests to check for vitamin deficiencies, diabetes, thyroid issues
• Imaging tests like MRIs, CT scans, or x-rays of potentially affected areas
• Nerve conduction studies to measure how well nerves transmit signals
• Possibly a lumbar puncture (spinal tap) to analyze spinal fluid

Based on the test results, your doctor can determine if an underlying medical condition is responsible for the numbness and recommend appropriate treatment.

Treatments for Numbness in Feet and Face

Treatment will depend on the cause, but may include:

• Prescription medications to reduce nerve inflammation or pain signals
• Physical therapy to improve strength and mobility
• Orthotics, splints, or braces to support affected areas
• Surgery to address compressed nerves or damaged tissues
• Vitamin supplements if a deficiency is found
• Lifestyle changes like diet, exercise, and stress reduction
• Alternative therapies like acupuncture, massage, chiropractic care

Gaining control over any underlying medical conditions, like diabetes or autoimmune disorders, can also help minimize numbness.

When to See a Doctor

You should make an appointment with your doctor if you experience:

• Numbness that appears suddenly or progresses rapidly
• Loss of sensation accompanied by severe pain
• Numbness not limited to just the feet or face
• Numbness combined with muscle weakness
• Numbness on only one side of the body or face
• Numbness following an injury or blow to the head or back

Prompt medical evaluation is key to determining the cause and initiating any required treatment before permanent nerve damage can occur.

Coping with Numbness Symptoms

While waiting for a diagnosis and treatment plan, try these tips for managing numbness:

• Massage and rub affected areas to improve circulation
• Avoid exposing numb skin to extreme temperatures or trauma
• Wear shoes with padded soles and toe protectors if feet are numb
• Use facial exercises to stimulate nerves if face is numb
• Reduce stress through relaxation techniques
• Join a support group to find coping strategies

Learning what triggers your numbness and avoiding exacerbating factors can help reduce frequency and severity of symptoms.

When to Worry About Numbness

Occasional brief numbness in the feet or face is usually not concerning. But seek medical advice if numbness is persistent, spreading, or impacting your daily activities. Prompt diagnosis and treatment can often reverse numbness and prevent long-term issues.

While multiple sclerosis and other neurological disorders can sometimes contribute to numbness, dont assume that is the cause without consulting your doctor. In many cases, alternate explanations like nutrient deficiencies, fractures, or trapped nerves may be responsible and more easily correctable.
