Pain on one side of the face symptoms

Sensation in the face is controlled by the trigeminal nerve, the fifth and largest cranial nerve of the body, and its many branches. There are many different components of the face — from muscles and bones to arteries and glands. These can all become disrupted, damaged, or injured, and result in facial pain that can be debilitating and sometimes difficult to resolve.

Common characteristics of one-sided facial pain

Pain on one side of the face can vary in quality. Depending on the cause, your facial pain may feel:

  • Sharp or dull
  • Burning or aching
  • Constant or intermittent
  • Localized or generalized
  • Electric/shock-like

Other symptoms

Since the quality of facial pain can take many forms, it may be difficult to figure out what other symptoms are associated. The following are common symptoms people with one-sided facial pain also experience:

Regardless of the combination of symptoms, one-sided facial pain often requires you to make an appointment with a physician. He or she can determine the cause and the best course of treatment.

Pain on one side of the face causes

The causes of one-sided facial pain vary widely due to the many components of the face that can become damaged, injured, or inflamed. These include neurologic, infectious, structural, and traumatic causes.

Neurologic causes

Neurologic causes of pain on one side of the face may include the following.

  • Neuropathic: The word neuropathic refers to a disruption in nerve functioning. One-sided facial pain can be caused by malfunction of the trigeminal nerve. In most cases, the exact mechanism causing the trigeminal nerve to malfunction is never diagnosed, but there are many diagnosable causes of trigeminal nerve dysfunction that this article will also discuss in depth.
  • Central: Central neurologic causes are those related to lesions or dysfunction in the central nervous system. Such pain can often happen after strokes or be due to conditions such as multiple sclerosis. Causes such as headaches and migraines can also be associated with one-sided facial pain. For example, people who suffer from migraines may experience an aura (a visual or sensory warning sign) on one side of the face before a migraine or a migraine may affect only one side of the face.

Infectious causes

Infection-related causes of pain on one side of the face may include the following.

  • Bacterial: Many bacteria can affect parts of the head, such as the teeth and sinuses, and indirectly cause one-sided facial pain. For example, a bacterial infection of a tooth that results in an abscess can lead to swelling and discomfort in the face. Bacterial infection of the eye can cause pain that radiates to include the face. Furthermore, specific bacteria such as the bacteria causing Lyme disease can affect nerves of the face.
  • Viral: Certain viruses are inclined to infect and attack the nerves of the face. Herpes zoster, the virus that causes shingles, can lay dormant in the trigeminal nerve and resurface to cause a painful, blistering rash of the face. Furthermore, the pain can recur even after the rash is treated and goes away in a condition known as post-herpetic neuralgia. Viruses can infect the same parts of the face that bacteria can infect, especially the sinuses and eyes.

Structural causes

Structural causes of pain on one side of the face may include the following.

  • Musculoskeletal: Pain and dysfunction in the muscles that control chewing and movement of the jaw can result in debilitating one-sided facial pain that is easily triggered by common actions such as eating breakfast or yawning.
  • Obstruction: Many conditions may obstruct or put direct pressure on the trigeminal nerve to cause pain or nerve dysfunction. For example, the presence of a salivary stone that obstructs the salivary gland may cause facial swelling that puts pressure on the trigeminal nerve causing pain.

Traumatic causes

Trauma-related causes of pain on one side of the face may include the following.

  • Iatrogenic: Iatrogenic is a term that describes a problem caused by medical intervention or treatment. Direct injury to the trigeminal nerve due to surgical trauma or treatment for trigeminal neuralgia can result in a condition called Anesthesia Dolorosa (painful, post-traumatic trigeminal nerve dysfunction) that is characterized by one-sided facial or oral pain.
  • Other injury: It is important to remember that one-sided facial pain can be due to direct injury to the face that may result in a fracture or bruise. Large bruises and deformities are a clear cause of any facial pain you be experiencing, but also take note of any smaller cuts or lesions on the face that could be responsible for your symptoms.

Acute viral sinusitis

Acute viral sinusitis, also called viral rhinosinusitis or "sinus infection," occurs when viruses take hold and multiply in the sinus cavities of the face.

It is most often caused by the same viruses that cause the common cold and spreads the same way, through an infected person's coughing or sneezing.

Because children have small, underdeveloped sinuses, this illness is far more common in adults.

Symptoms include clear nasal discharge (not greenish or yellowish,) fever, and pain if facial sinuses are pressed.

If there is rash, severe fatigue, or neurologic symptoms (seizures, loss of sensation, weakness, or partial paralysis,) see a medical provider to rule out more serious conditions.

Diagnosis can usually be made through history and examination alone.

Antibiotics only work against bacteria and cannot help against a viral illness. Therefore, treatment consists of rest, fluids, and fever/pain reducers such as ibuprofen. (Do not give aspirin to children.) Symptoms of viral sinusitis last for about seven to ten days. As with the common cold, the best prevention is frequent and thorough handwashing.

Rarity: Common

Top Symptoms: headache, cough, sinusitis symptoms, sore throat, congestion

Symptoms that always occur with acute viral sinusitis: sinusitis symptoms

Symptoms that never occur with acute viral sinusitis: being severely ill

Urgency: Self-treatment

Viral throat infection

A sore throat is most often caused by the same viruses that cause influenza and the common cold. The illness spreads when an infected person coughs or sneezes, and then someone else inhales the airborne virus or touches a surface where it has landed.

Those most at risk for viral sore throat are children, smokers, those who work indoors with others, and anyone with a weakened immune system.

Symptoms include throat irritation; pain when swallowing or talking; red, swollen tonsils; fever; body aches; and cold-like symptoms of cough, sneezing, and runny nose.

If symptoms do not clear up within 24 hours – especially in children – a medical provider should be seen. A persistent sore throat can be a symptom of serious illness such as mononucleosis, measles, chickenpox, or croup.

Diagnosis is made through physical examination and throat swab.

Treatment involves rest, fluids, and over-the-counter pain relievers. Do not give aspirin to children. Antibiotics only work against bacteria and cannot help against a viral illness.

The best prevention is frequent and thorough handwashing.

Temporomandibular joint (TMJ) dysfunction disorder

Temporomandibular joint (TMJ) dysfunction disorder refers to long-term pain and dysfunction in the TMJ, the joint that connects the upper and lower jawbones.

The TMJ is a complex joint with complicated movements and is subject to strain and injury. Symptoms may come and go for no apparent reason. Misalignment of the teeth and jaw, and tooth grinding, are no longer believed to be a cause. Women seem to be more susceptible than men.

TMJ disorder has three types:

  • Pain or discomfort in the muscles controlling the TMJ.
  • Dislocation or injury to the jawbone.
  • Arthritis of the TMJ.

Diagnosis is made through patient history, physical examination, and imaging. The goal is to rule out other causes such as sinus infection or facial nerve damage.

Due to the difficulty of diagnosing TMJ disorder, treatment begins with conservative methods that do not permanently change the jaw or teeth. Ice packs, soft foods, gentle stretching of the jaw muscles, and reducing stress are all encouraged. Short-term pain medications may be used. Splints, Botox, implants, and surgery are not recommended.

Rarity: Common

Top Symptoms: dizziness, pain, restricted movement, and clicking sounds from jaw, history of headaches, jaw pain, pain in the back of the neck

Symptoms that always occur with temporomandibular joint (tmj) dysfunction disorder: pain, restricted movement, and clicking sounds from jaw

Urgency: Primary care doctor

Sinus headache

Sinus headache, also called sinusitis or rhinosinusitis, is caused by either a bacterial or a viral infection of the sinuses (open spaces) behind the eyes and nose.

Symptoms include fever; thick nasal discharge which may be clear, white, greenish or yellowish; some loss of sense of smell; foul-smelling breath; and pain, congestion, and pressure over the sinus areas of the face, especially if bending forward or lying down.

A self-diagnosed "sinus headache" very often turns out to be a migraine headache with a few sinus symptoms. This requires very different treatment from an actual , and is an important reason to see a medical provider about any sort of ongoing headaches.

Diagnosis is made through patient history, physical examination, and sometimes CT scan or MRI of the head to look for changes in the sinuses.

A true sinus headache, if caused by a bacterial infection, will be treated with antibiotics. If caused by a viral infection, the symptoms can be treated with over-the-counter pain relievers and alternating hot and cold compresses.

Rarity: Common

Top Symptoms: headache, headache that worsens when head moves, facial fullness or pressure, mucous dripping in the back of the throat, sinus pain

Symptoms that always occur with sinus headache: headache

Symptoms that never occur with sinus headache: fever, being severely ill, sore throat, muscle aches, cough, drooping eyelid, wateriness in both eyes

Urgency: Self-treatment

Myofascial pain syndrome

Myofascial pain syndrome is also called chronic myofascial pain (CMP.) Pressure on certain points of the muscles causes referred pain, meaning the pain is felt elsewhere in the body.

The cause is believed to be muscle injury through overuse, either from sports or from a job requiring repetitive motion. Tension, stress, and poor posture can also cause habitual tightening of the muscles, a form of overuse.

This overuse causes scar tissue, or adhesions, to form in the muscles. These points are known as trigger points, since they trigger pain at any stimulus.

Symptoms include deep, aching muscular pain that does not go away with rest or massage, but may actually worsen. There is often difficulty sleeping due to pain.

Myofascial pain syndrome should be seen by a medical provider, since it can develop into a similar but more severe condition called fibromyalgia.

Diagnosis is made through physical examination and applying mild pressure to locate the trigger points.

Treatment involves physical therapy, pain medications, and trigger point injections. In some cases, acupuncture and antidepressants are helpful.

Rarity: Common

Top Symptoms: dizziness, spontaneous shoulder pain, pain in the back of the neck, tender muscle knot, general numbness

Symptoms that always occur with myofascial pain syndrome: tender muscle knot

Urgency: Primary care doctor

Infection of the salivary duct (sialadenitis)

The ducts that create saliva can be infected by bacteria and is typically found after surgery in the mouth and in the elderly that take medications that slow saliva production.

You should visit your primary care physician or an urgent care today. In the most minor situation, you would need antibiotics for 10 days while the doctors identify the type of bug it is. In more severe cases, you might need to go to the hospital for antibiotics given through the blood.

Rarity: Rare

Top Symptoms: fever, chills, swelling on one side of the face, pain on one side of the face, swollen jaw

Urgency: Hospital emergency room


Cellulitis is a bacterial infection of the deep layers of the skin. It can appear anywhere on the body but is most common on the feet, lower legs, and face.

The condition can develop if Staphylococcus bacteria enter broken skin through a cut, scrape, or existing skin infection such as impetigo or eczema.

Most susceptible are those with a weakened immune system, as from corticosteroids or chemotherapy, or with impaired circulation from diabetes or any vascular disease.

Symptoms arise somewhat gradually and include sore, reddened skin.

If not treated, the infection can become severe, form pus, and destroy the tissue around it. In rare cases, the infection can cause blood poisoning or meningitis.

Symptoms of severe pain, fever, cold sweats, and fast heartbeat should be seen immediately by a medical provider.

Diagnosis is made through physical examination.

Treatment consists of antibiotics, keeping the wound clean, and sometimes surgery to remove any dead tissue. Cellulitis often recurs, so it is important to treat any underlying conditions and improve the immune system with rest and good nutrition.

Rarity: Uncommon

Top Symptoms: fever, chills, facial redness, swollen face, face pain

Symptoms that always occur with cellulitis: facial redness, area of skin redness

Urgency: Primary care doctor

Carotid artery dissection

A carotid artery dissection is the tearing of the walls of the carotid arteries, which deliver blood to the brain from the aorta. This is a medical emergency.

Call 911 immediately. Diagnosis is done by CT or MRI, and treatment involves anti-clotting medication for at least 3-6 months. Surgery may be necessary for those who can't get this medication.

Bruise of the face

A bruise is the damage of the blood vessels that return blood to the heart (the capillaries and veins), which causes pooling of the blood. This explains the blue/purple color of most bruises. Bruises of the back are common, given how exposed this area of the body is.

You can treat this at home with rest (exercise as tolerated) and ice (10-20 minutes at a time).

Rarity: Common

Top Symptoms: swelling on one side of the face, head or face injury, painful face swelling, warm and red face swelling, face bruise

Symptoms that always occur with bruise of the face: head or face injury

Urgency: Self-treatment

Acute bacterial sinusitis

Acute bacterial sinusitis, also called bacterial rhinosinusitis or "sinus infection," has symptoms much like viral rhinosinusitis but a different treatment.

Any sinusitis usually begins with common cold viruses. Sometimes a secondary bacterial infection takes hold. Like cold viruses, these bacteria can be inhaled after an infected person coughs or sneezes.

Anyone with viral sinusitis, upper-respiratory allergy, nasal passage abnormality, lung illness, or a weakened immune system is more prone to bacterial sinusitis.

Symptoms include thick yellowish or greenish nasal discharge; one-sided pain in the upper jaw or teeth; one-sided sinus pain and pressure; fatigue; fever; and symptoms that get worse after first improving.

See a doctor right away for severe headache, high fever, stiff neck, or vision changes. These can indicate a medical emergency.

Diagnosis is made with a simple examination in the doctor's office.

Bacterial sinusitis can be treated with antibiotics, but this is not always necessary.

Often rest, fluids, and over-the-counter pain relievers and decongestants are enough.

Prevention is done through good lifestyle and hygiene to keep the immune system strong.

Rarity: Common

Top Symptoms: fatigue, headache, cough, sinusitis symptoms, muscle aches

Symptoms that always occur with acute bacterial sinusitis: sinusitis symptoms

Symptoms that never occur with acute bacterial sinusitis: clear runny nose, being severely ill

Urgency: Primary care doctor

Pain on one side of the face treatments and relief

Treatment for your facial pain will most likely require a healthcare professional. Make an appointment with your physician in order to receive a diagnosis and get appropriate treatment. Depending on the diagnosis, your physician may recommend the following treatment options:

  • Anticonvulsants: Many anticonvulsant medications, such as gabapentin (Neurontin) or carbamazepine (Tegretol), more commonly used for seizures, are also used to combat nerve pain.
  • Antibiotics: If your facial pain is due to bacterial causes, your physician will prescribe the appropriate antibiotic medication to combat your symptoms. Viral causes will not resolve with antibiotics, and your physician will most likely suggest supportive remedies if that is the case.
  • Surgery: There are surgical procedures that can destroy nerve fibers in the face to reduce pain symptoms, especially for the neurological causes of facial pain. Talk with your physician about this option and assess if it is the best option for you.

FAQs about pain on one side of the face

Recurring facial issuePosted February 16, 2024 by R.
I have experienced facial pain randomly for years, it generally is on one side. Last Thursday, I had this prickly, numbing somewhat tingly feeling on right side with a headache that was on upper right of head. I actually blew blood out that one side. One day and it’s gone. Followng Monday blew nose and a lot of blood, no other drainage or anything is going on. One week and day later, Friday, left side is same as right was week ago. With a fever blister on lip this time. Haven’t been to doctor, because I’ve found that after you get appointment your symptoms have disappeared. I am thankful it does go away. I’ve had it last for as long as three days in past.
