Bell’s Palsy – Causes, Symptoms And Treatment

Bell’s palsy is a debilitating neurological condition characterized by weakness of the muscles on one side of the face. This condition is often short-lived, lasting 3 to 6 months. But it can leave a person with a slightly deformed facial appearance. It can also cause changes in taste, sensitivity to sound, and saliva and tear production. Experts are unsure of what causes this disease, but it appears to involve the seventh cranial nerve, which controls facial muscles.

While Bell’s Palsy is rare, it can also be hereditary, most common in pregnant women and sick people. In this case, treatment for the condition may not be necessary, but it is often recommended in cases where the symptoms have recurred. If the condition is left untreated, it can result in permanent damage to the facial nerve. And even after the treatment, the condition has a tendency to return.

What Causes Bell’s Palsy

1. Elevated Blood Pressure leading to stroke

2. Severe Facial Injuries Or Physical trauma

3. Sarcoidosis( Organ Inflammation/Infection).

4. Lyme Disease

5. Although the exact cause of inflammation is unknown, it is commonly caused by a virus. The viruses responsible for chickenpox and cold sores(Varicella-Zoster Virus/Herpes Simplex Virus) are among the most common causes of Bell’s Palsy. After these viruses have been shed, they remain in nerve roots, and multiply and cause the symptoms. This is why treatment for Bell’s Palsy is critical. Some people are more prone to formulating this condition than others.

Symptoms of Bell’s Palsy

As with any disorder, Bell’s Palsy can result in partial or complete paralysis in the affected face. Symptoms vary in severity but may range from mild weakness to total facial paralysis. Early symptoms of Bell’s Palsy may occur abruptly and are common in the early stages of the condition. Symptoms may appear at any time, including while you’re sleeping, when you try to eat, or when you’re trying to drink.

Symptoms of Bell’s Palsy may be mild or severe, but they are indicative of a condition that can cause severe facial weakness. These include weakness in one or both sides of the face. They are often associated with a

i. Dry and swollen eye

ii. Difficulty with speech.

iii. loss of taste in the front of the tongue.

iv. migraine headache

v. Some people may experience difficulty closing one eye or even drooping facial muscles.

vi. Early symptoms of Bell’s Palsy include difficulty closing one or both eyes or blinking. Protecting the eye with artificial tears is crucial during the early stages of the condition. When you sleep, tape the affected eye shut. Using artificial tears can prevent damage to the cornea. Using an eye patch while sleeping will also help protect the affected eye. And always wear eye protection.

vii. You may also experience other symptoms of Bell’s Palsy, including Sound Sensitivity or hearing loss (Hyperacusis).


1. The first step in diagnosing Bell’s palsy is to exclude other potential causes. Recent rashes, arthralgias, medications, and tick exposure should not be the cause. A physical examination is necessary to rule out any other conditions that could cause facial weakness. The parotid gland and the tympanic membrane should be assessed as well. After the exclusion of these causes, a final diagnosis should be made.

2. During the first few months, About 70% of people with Bell’s palsy recover spontaneously. However, if it lasts longer than this, your doctor will order further tests to rule out other causes. A specialized test called electromyography may be necessary to determine the exact level of nerve damage. Once diagnosed, most people will recover within three weeks. However, some individuals may still experience weakness in the affected side of the face for some time.

4. Nasopharyngeal Stenosis (NPs) can successfully manage the symptoms of Bell’s palsy as part of primary care. Nasopharyngeal Stenosis (NPs) should complete a comprehensive physical examination and history to determine the underlying cause. Pharmacologic treatment may be initiated to alleviate the symptoms and shorten their course. Nasopharyngeal Stenosis (NPs) should be aware of the prognosis for Bell’s palsy and should communicate expected outcomes to clients to reduce anxiety.


1. Treatment for What Causes Bell’s Palsy counts on the harshness of the symptoms. If your eyelid cannot close, you should seek medical attention immediately. In addition to surgery, other methods can help you deal with the symptoms of Bell’s Palsy. You can try facial exercises to regain control over your eye muscles. Try lifting the eyebrow with your fingers and gently massaging your eyelid. Alternately, you can gently squeeze the eyelid closed and open it wide.

2. Surgery is not the first option for Bell’s Palsy treatment, but it may be necessary in some cases. During the initial stages, surgery should be avoided because the symptoms are likely to return. Surgery is often necessary when treatment fails, or complications occur. But it’s worth considering if surgery is your only option.

3. Healthcare professionals can determine if a patient has Bell’s palsy based on the symptoms and medical history. Examine the muscles around the eye to look for weakness. Nerve conduction studies or muscle tests may also help determine if there’s any damage to the nerve. Magnetic Resonance Imaging (MRI) scans may show whether facial nerves have been damaged. Treatment may involve eyelid protection, tape, or antiviral drugs.

4. A physiotherapist or speech-language therapist can provide facial rehabilitation therapy. Treatment is often aimed at alleviating the symptoms and preventing the condition from progressing. Botulinum toxin injections can reduce overactivity in the muscles and relax involuntary facial movements. Eventually, patients can resume a normal, balanced facial expression.

5. A doctor may prescribe corticosteroids or antiviral medication to reduce swelling and make the nerve function return. Corticosteroids work best when taken within 72 hours of symptoms. For best results, doctors should prescribe these drugs as early as possible. Otherwise, the patient may continue to experience complications. This treatment is not suitable for all cases. You should consult with your doctor for more information. If you suspect you have Bell’s Palsy, your doctor will prescribe a medication that is safe for you and that can help you get back to your old self.
