Bell’s Palsy: How to Recover From This Puzzling Facial Paralysis

The good news is, it's usually only temporary

Imagine looking in the mirror one day and noticing that your face seems to be sagging on one side, and your smile looks a little crooked. By the next day, you realize you can’t move an entire side of your face.

This facial paralysis, called Bell’s palsy, happens to tens of thousands of people each year. The good news is that it’s generally not permanent, but it can be a very scary experience nonetheless.

Part of the face becomes paralyzed because of damage or inflammation in the nerve that controls the muscles on either side of the face – the muscles you use to smile, blink and scrunch up your nose.

Doctors think that the nerve damage or inflammation might be triggered by a viral infection, like the herpes simplex virus or the varicella zoster virus, which causes chickenpox and shingles, says neurologist MaryAnn Mays, MD.

She says that many people initially mistake Bell’s palsy for a stroke. Although they produce a common symptom (weakness in one side of the face), the two aren’t actually related, and how they’re treated is very different.

Bell’s palsy vs. stroke

Bell’s palsy should be treated right away, but it isn’t necessarily an emergency.

A stroke, on the other hand, is a medical emergency. If you or someone you know experience facial droop along with any other symptoms of stroke, such as numbness, weakness, slurred speech, double vision or dizziness, or if the symptoms aren’t clear-cut, call 911. It’s better to be safe than sorry.

Dr. Mays says there are a few additional signs that can help distinguish one from the other:

  • A stroke comes on suddenly, whereas Bell’s palsy usually develops over the course of hours or days.
  • Generally, it’s the lower part of the face that becomes weak when someone is having a stroke. With Bell’s palsy, both the lower and upper part of the face will be affected, so it may be hard to blink or move the eyebrows.

Other symptoms that someone with Bell’s palsy might experience include:

  • Headache or pain behind the ear
  • Loss of taste on one side of the tongue
  • Sensitivity to sound in one ear
  • Excessive tears in one eye

Start treatment within 3 days

After doing an exam and diagnosing Bell’s palsy, a primary care doctor or urgent care clinic can prescribe an oral steroid such as prednisolone to help ease the swelling around the nerves in the face.

The doctor might also prescribe an anti-viral medicine in addition to the steroid if they suspect it’s related to an underlying viral infection.

Treatment is most successful when it begins within 72 hours, Dr. Mays says, so it’s important to see a doctor quickly.

Tips for recovery

How long does it take for someone with Bell’s palsy to be able to move their face again?

Everyone is different, but, “as a rule of thumb, usually within three weeks people will start to get some improvement,” Dr. Mays says.

For some people, though, recovery may take a few months.

In the meantime, it’s important to protect the eye on the side that’s paralyzed, since it won’t be able to protect itself by blinking or closing.

“We want to make sure that the patient can fully close their eye when they’re sleeping – we recommend covering the eye up with either a patch or a piece of tissue or hanky taped over the eye so that they don’t get any scratches on the cornea,” Dr. Mays says.

Most people will not need treatment beyond medication. Some people use additional treatments to help their recovery, but Dr. Mays notes that there aren’t a lot of scientific studies showing that these methods do speed up or improve recovery. They include:

  • Facial exercises
  • Electrical stimulation
  • Acupuncture
  • Massage

If symptoms haven’t cleared up after eight weeks, a doctor might want to do an MRI. Rarely, the facial nerve loses its way as it heals and grows back. This can lead to unintentional movements of facial muscles, like the eye blinking when someone smiles.

But usually, Bell’s palsy goes away and isn’t a sign that something else is wrong. By taking prednisolone as instructed, caring for the affected eye and following up with a doctor, most people can recover and get back to their normal quality of life.
