Numbness and a tingling sensation can occur in any part of the body, such as the hands, feet and even the face. Numbness on the face can be caused by several diseases that need to be aware of. Numbness in one side of the face occurs when the facial nerve is damaged. Numb facial muscles usually appear loose with limited movement or even complete paralysis. Depending on the cause, facial paralysis can be short or long lasting.

Face Numbness One Side Causes

There are so many factors that can cause facial paralysis. These factors can come from birth or due to health problems that occur during life.

Here are some factors that often cause numbness on one side of the face:

1. Congenital

Facial paralysis from birth is usually caused by the fetus’s facial nerves and / or muscles not developing properly in the uterus.

The baby’s face can also be lopsided if the facial nerve is traumatized and damaged during childbirth.

In some cases, facial paralysis can be caused by hemifacial microsomia (HFM). This condition is related to the growth of abnormal cells on the face of the fetus while it is in the womb. However, the exact cause is unknown.

2. Bell’s palsy

Bell’s palsy is the most common cause of facial numbness. This disease occurs when the facial nerve becomes inflamed, swollen, or compressed. Nerve disorders make the muscles on the face become lowered and immobilized.

The exact cause of Bell’s palsy is not known exactly, but experts believe that inflammation of the facial nerve is triggered by a viral or bacterial infection. Bell’s palsy usually appears suddenly, and then gets better after a few weeks.

3. Stroke

Stroke is the effect of stopping blood flow to the brain. Brain cells always need oxygen rich blood.

Lack of blood supply for just a few minutes can cause death to the brain cells and nerves around it.

Stroke can not only cause numbness in one face, but also hands, feet, and the whole side of the body. Stroke sufferers must get medical help immediately to prevent further complications.

4. An impact on the skull or face

The facial nerve covers the entire face to the right and left of the skull. Hard impact on the area can put pressure on the facial nerve and cause damage. As a result, one side of the face becomes numb.

This condition generally occurs after a person has had a vehicle accident or injury. If paralysis of the face occurs immediately after the impact, the patient usually needs to undergo surgery to reduce pressure on the facial nerve.

5. Tumor

Numbness on one side of the face can also be caused by tumors on the head or neck. Tumors are usually benign and can be removed easily. However, there are also cancerous tumors that must be eradicated immediately.

If the tumor is located very close to the facial nerve, removal of the tumor can also cause temporary or permanent paralysis on one side of the face. Therefore, patients should consult a doctor before choosing to undergo surgical removal of the tumor.

Paralysis on one side of the face is certainly a cause for concern. The reason is, the medical conditions that cause it can lead to long-term impacts or more serious complications.
