Numbness of the cheek is not a very common problem. However, if your left cheek is numb, then the cause should be established by the doctor. Therefore, if such a symptom occurs, be sure to contact a medical institution. In some cases, a similar symptom may indicate the development of a serious problem. But for what reasons does the left cheek go numb? How to deal with this symptom? We will talk about this in the article.
Possible reasons
If the left cheek is numb, the reason may lie in squeezing the face during sleep. In such situations, the blood supply to this area worsens. But for what reasons does the left cheek go numb yet? They may be as follows:
- Neuritis of the occipital or facial nerve.
- Inflammation of the lymph nodes, as well as diseases of the lymphatic system.
- Hypertensive infection.
- Oncological neoplasms in the facial section. The fact is that such neoplasms, as well as their metastases, are able to compress nerves, thereby worsening innervation.
- Insufficient amount of vitamins E and B in the body
- Face trauma, surgery, flux.
- Vegetovascular dystonia, hypertension.
- Stroke.
- Osteochondrosis.
- Migraine.
- Hypothermia.
- Damage or inflammation of the parotid salivary gland.
- Exposure to anesthetics, which are used for FGDS, as well as tooth extraction.
- ENT diseases, which should include rhinitis, sinusitis and others.
- Multiple sclerosis, as well as other diseases of the peripheral nerves.
- Diseases of the gums and teeth.
- Diabetic neuropathy.
Now consider symptoms in some of the cases.
Neuralgia
We continue to consider why the left cheek is numb, the causes of this symptom. If it consists in neuralgia of the sensory nerves that innervate the face, then numbness of the face occurs, as well as some of its parts: nose, temple, chin. The reason for the development of neuralgia is hypothermia, inflammation, trauma, and herpes infection. These factors disrupt the ability to transmit momentum along the nerve fiber, which leads to numbness.
Lymph congestion
Often the left cheek and lip are numb due to the occurrence of lymph stagnation. Inflammation of the lymph nodes is a consequence of the penetration of the infection into the human body, as well as its delay directly in the lymphatic system. In parallel, puffiness occurs, which compresses the nerves that provide sensitivity on the face. Thus, numbness occurs.
Sinusitis
This disease is an inflammation of the maxillary sinuses, which is provoked by a respiratory acute infection. The cause may also be an infection from the gingival pockets or carious teeth. All these unpleasant ailments can provoke numbness of the cheek or other parts of the face.
Avitaminosis
Nicotinic acid, vitamins of group B, E, cobalamin, pyridoxine play an important role in ensuring the functioning of the entire nervous system. A lack of these elements can be observed with the development of diseases of the digestive system: hepatitis, gastritis, helminthic invasion in the small intestine, enteritis, giardiasis. A deficiency of these elements can lead to numbness, as well as tingling, not only in the cheek area, but also in the chin and lips.
Damage, operation
Post-traumatic, postoperative edema causes circulatory disorders. Numbness of the face also appears. In addition to superficial damage, a secondary infection can develop, the development of an abscess and phlegmon.
Stroke, as well as other cerebrovascular disorders
When a hemorrhage occurs in the brain, the centers are damaged that receive information about the temperature and pain irritation of the skin. That is why a stroke is a likely cause of numbness in some parts of the face.
Anesthetics
"Novocaine", "Lidocaine", as well as other drugs that are used for pain relief in endoscopy, dentistry, can cause disturbances in the conduct of nerve impulses along sensitive nerves. It is also possible the development of an allergic reaction, which leads to thinning of nerve fibers.
Multiple sclerosis
When the left arm and cheek are numb, the cause is often multiple sclerosis. Any ailments of the peripheral nerves appear with a viral infection, food allergies, as well as immunodeficiency. With multiple sclerosis, paralysis of the limbs, hearing loss, blindness are also possible. A disease progresses over time if it is not stopped on time.
How to treat?
So, we figured out for what reasons the left cheek is numb. How to treat this symptom? First of all, to find out the exact cause, you need to visit your doctor. Depending on the reason the left cheek is numb, the treatment will be prescribed by your specialist. So, in more detail we will analyze what methods of therapy will be used in a particular case, which is accompanied by the appearance of numbness of the left cheek:
- As a rule, with a decrease in sensitivity, B vitamins are prescribed. In parallel, electrophoresis is performed with hyaluronidase, nicotinic acid, vitreous body, aloe, and other biologically active stimulants.
- If some inflammatory disease has been identified, for example, periodontal disease, carious teeth, then their therapy is carried out. To do this, dead teeth are removed, oral cavity sanitation is done.
- If numbness of the cheek appeared due to sinusitis, then this disease is treated with lavage, antibiotics, which are prescribed by an ENT specialist.
- In the case of neuralgia, non-steroidal anti-inflammatory drugs are used, as well as reflexology. In parallel with this, a specialist can prescribe electrophoresis or acupuncture.
- For the treatment of multiple sclerosis, special hormones, immunosuppressants, are prescribed to suppress the immune attack.
- In case of hemorrhage, the patient should be hospitalized urgently, after which antihypoxic drugs are prescribed. Ischemic stroke is provoked by arterial thrombosis, which can be eliminated by using fibrinolytic drugs, as well as anticoagulants.
- If numbness occurred after the use of energy, then, as a rule, this symptom disappears on its own. In such situations, some treatment is not required.

Conclusion
If your left cheek is numb, then this is an occasion to seek help at a medical institution. The fact is that this symptom can be a sign of the development of some dangerous disease. Ignoring such a sign can provoke very unpleasant consequences, up to a fatal outcome. When the doctor finds the main cause of this disorder, appropriate treatment will be prescribed.
