Symptoms of facial numbness
Facial numbness is the inability to feel normal sensations on all or part of the face. This phenomenon may be quite noticeable to you and somewhat alarming. However, it is possible for facial numbness to be first discovered by a medical provider using objects such as a cotton ball to test sensation. Facial numbness can occur in isolation, but there may be other areas of the body with abnormal sensation or additional symptoms. The numbness can develop gradually or suddenly, depending on the cause.
Facial sensation depends on signals sent by a large cranial nerve located in the face called the trigeminal nerve. These signals travel through the brainstem and are interpreted in the brain. A problem in the trigeminal nerve, the pathway from the nerve to the brain through the brainstem, or the brain itself can contribute to facial numbness.
Characteristics of facial numbness
Causes of facial numbness
Causes of facial numbness are described below from most to least common, including neurological abnormalities, injuries, other medical conditions, or a psychiatric cause.
Causes of facial numbness related to neurological abnormalities may include:
- Stroke: A stroke (decreased blood flow caused by a clot or bleeding) in the brain or brainstem can cause sudden-onsetone-sided facial numbness. Other symptoms will also be present, such as weakness, clumsiness, and numbness in the arm and leg. The affected limbs will be on the same or opposite side of the facial numbness depending on the location of the stroke.
- Tumors: A benign or malignant tumor affecting the sensory pathway for facial sensation can cause numbness. This can occur with a tumor in the head and neck area, brain, or one of the cranial nerves near the trigeminal nerve. Depending on the location of the tumor, other possible symptoms include a spinning sensation, hearing loss, and enlarged lymph nodes in the neck.
- Other neurological disorders: Trigeminal neuralgia, a condition caused by damage to the trigeminal nerve, can cause facial numbness. Numbness will be followed by an episode of severe facial pain. Disorders such as multiple sclerosis (MS) can also lead to facial numbness, often with other neurological symptoms present.
Injuries that can lead to facial numbness may include the following.
- Facial trauma: A fracture or swelling after a facial injury can cause numbness.
- Surgery: Rarely, an injury to the trigeminal nerve during facial surgery (such as a facelift) can produce facial numbness.
Other medical conditions
Other medical conditions that can lead to facial numbness may include:
- Low calcium: An abnormally low level of calcium (hypocalcemia) in the body can cause neurological symptoms including numbness or tingling around the mouth.
- Scleroderma: Facial numbness is one of the most common neurological complications of the connective tissue disease scleroderma. Tingling and pain are usually also present.
A feeling of numbness in the body, including in the face, can be perceived in the absence of a physical cause. A physical exam from a medical provider can usually determine whether facial numbness is psychological in nature.

Panic or anxiety attack(s)
Panic or anxiety attacks are sudden feelings of intense fear or stress without true danger. Symptoms usually peak and then decrease within minutes. One may feel as if they are losing control or have physical symptoms like sweating or a racing heart. A panic attack can be a very scary experience and should be taken seriously.
Symptoms that always occur with panic or anxiety attack(s): anxiety or anxiety/panic attacks
Urgency: Primary care doctor
Bell’s palsy can present as acute or chronic facial paralysis. This paralysis is usually sudden in onset and worsens over the course of 48 hours. Resolution of symptoms usually occurs within two weeks to six months but permanent paralysis can rarely occur. Symptoms of this condition are a result of the paralysis of facial muscles. This paralysis usually occurs only on one side of the face. The cause of Bell’s palsy is inflammation or damage to the facial nerve, also known as cranial nerve VII. This nerve controls the muscles of the face. Treatment is aimed at reducing inflammation or targeting the underlying cause of facial nerve paralysis.
Top Symptoms: arm weakness, facial numbness, arm weakness, hearing loss, pain on one side of the face
Symptoms that always occur with bell's palsy: face weakness, weakness in one side of the face
Urgency: Primary care doctor
Nose or sinus tumor
A tumor in the nose or one of the sinuses occurs due to abnormal growth of the cells lining the inside of the nose and sinuses. These tumors are rare and can cause symptoms like congestion or blockage, nose bleeds and sometimes facial pain or swelling.
Rarity: Ultra rare
Top Symptoms: new headache, congestion, vision changes, ear fullness/pressure, ear pain
Symptoms that never occur with nose or sinus tumor: improving congestion
Urgency: Primary care doctor
Stroke or tia (transient ischemic attack)
Transient ischemic attack, or TIA, is sometimes called a "mini stroke" or a "warning stroke." Any stroke means that blood flow somewhere in the brain has been blocked by a clot.
Risk factors include smoking, obesity, and cardiovascular disease, though anyone can experience a TIA.
Symptoms are "transient," meaning they come and go within minutes because the clot dissolves or moves on its own. Stroke symptoms include weakness, numbness, and paralysis on one side of the face and/or body; slurred speech; abnormal vision; and sudden, severe headache.
A TIA does not cause permanent damage because it is over quickly. However, the patient must get treatment because a TIA is a warning that a more damaging stroke is likely to occur. Take the patient to the emergency room or call 9-1-1.
Diagnosis is made through patient history; physical examination; CT scan or MRI; and electrocardiogram.
Treatment includes anticoagulant medication to prevent further clots. Surgery to clear some of the arteries may also be recommended.
Top Symptoms: dizziness, leg numbness, arm numbness, new headache, stiff neck
Symptoms that never occur with stroke or tia (transient ischemic attack): bilateral weakness
Urgency: Emergency medical service
Multiple sclerosis (ms)
Multiple sclerosis, or MS, is a disease of the central nervous system. The body's immune system attacks nerve fibers and their myelin covering. This causes irreversible scarring called "sclerosis," which interferes with the transmission of signals between the brain and the body.
The cause is unknown. It may be connected to a genetic predisposition. The disease usually appears between ages 20 to 50 and is far more common in women than in men. Other risk factors include family history; viral infections such as Epstein-Barr; having other autoimmune diseases; and smoking.
Symptoms include numbness or weakness in arms, legs, or body; partial or total loss of vision in one or both eyes; tingling or shock-like sensation, especially in the neck; tremor; and loss of coordination.
Diagnosis is made through patient history, neurological examination, blood tests, MRI, and sometimes a spinal tap.
There is no cure for MS, but treatment with corticosteroids and plasma exchange (plasmapheresis) can slow the course of the disease and manage symptoms for better quality of life.
Top Symptoms: severe fatigue, constipation, numbness, decreased sex drive, signs of optic neuritis
Urgency: Primary care doctor
Shingles is a painful rash that results when the varicella zoster virus (VZV) — the same virus that causes the chickenpox — becomes reactivated. It results in a painful rash of small fluid-filled blisters (vesicles) over a single strip of skin on one side of the body.
Facial numbness treatments and relief
Going to a medical provider for diagnosis and treatment of a medical condition is the best way to approach facial numbness. Home treatments are unlikely to be effective.
When facial numbness is an emergency
Some causes of facial numbness can be dangerous and require immediate evaluation and treatment, such as:
- Sudden, widespread numbness and/or weakness: Sudden-onset facial numbness along with other neurological symptoms such as numbness and/or weakness in other parts of the body require urgent care.
- Seizures or difficulty breathing: These symptoms are consistent with a severely low calcium level, which requires treatment to prevent cardiac arrhythmias and other complications.
- Facial injury: This requires urgent care when occurring with numbness, disfigurement, difficulty breathing, or any other significant symptoms.
When to see a doctor for facial numbness
In some cases, even if emergency care isn't necessary, you may need evaluation and treatment. Make an appointment with your medical provider if:
- Your facial numbness does not resolve or gets worse
- You are experiencing episodes of facial pain along with numbness
- You have gradually developed other neurological symptoms: Such as a spinning sensation, hearing loss, visual changes, or weakness
- You have enlarged lymph nodes in the neck
Your medical provider may prescribe one or more of the following treatments, depending on the cause of your facial numbness:
- Medication: This can treat an underlying disorder such as trigeminal neuralgia or multiple sclerosis.
- Therapy: A therapy program can identify and address underlying psychological difficulties that may be contributing to facial numbness.
- Surgery: Referral for surgical management of a tumor or trigeminal neuralgia that has not responded to other treatments.
FAQs about facial numbness
Can facial numbness be a sign of a stroke?
Numbness on one side of the face can be caused by a stroke. Facial numbness will not be the only symptom if a stroke is the cause. Other possible symptoms include numbness and/or weakness in the arm and leg, which can be on the same side or opposite side from the facial numbness depending on the location of the stroke. You should seek emergency treatment if you notice sudden onset of facial numbness, especially if you have any other neurological symptoms.
Why is my face numb only on one side?
Many causes of numbness will affect only one side of the face. A stroke occurs on one side of the brain or brainstem, so only one side of the face is affected by sensory abnormalities. Each side of the face has a trigeminal nerve, which communicates facial sensation to the brain; an abnormality of one of the trigeminal nerves will affect sensation only on the corresponding side. A tumor will cause facial numbness on only one side, while an injury could cause numbness on one or both sides depending on the location.
Will facial numbness eventually go away?
Many causes of facial numbness will resolve on their own or with treatment. Numbness after an injury will likely go away as healing occurs. If multiple sclerosis is the cause, sensation will typically return to normal, but treatment will be required to help prevent future neurological abnormalities. Numbness following a stroke may resolve over time, but the prognosis is unpredictable.
What causes facial numbness after an injury?
Numbness of part of the face can occur after a severe trauma, such as a sports injury or car accident. If the numbness starts directly after the injury, it may be caused by nerve damage that occurred via a fracture of one of the facial bones. Facial numbness that develops gradually after an injury is more likely caused by post-traumatic swelling.
Can facial numbness be a sign of cancer?
Rarely, cancer can be the cause of facial numbness. The trigeminal nerve, which communicates sensory signals from the face to the brain, can be damaged by a tumor of the head and neck or a neighboring nerve. A brain tumor can also cause loss of facial sensation. Facial numbness is unlikely to be the only sign of a tumor: other possible symptoms include hearing loss, a spinning sensation, and enlarged lymph nodes in the neck.
