y spectrum, from mild weakness to total paralysis.
"Bell's palsy is time-limited and patients generally recover quickly—in a matter of weeks," Dr. Hinman says. "On the spectrum of neurologic disease, it is generally not serious, although severe cases can cause permanent facial paralysis."
How to treat Bell's palsy
Steroids and antiviral medications are the go-to treatment, Dr. Hinman says. "Sometimes an eye patch is needed if the eyelid muscles are impaired and the eyelid cannot close completely," he adds. It's important to keep the eye moist with lubricating eye drops and protect it from debris and injury, particularly at night.
NINDS also recommends analgesics such as aspirin, acetaminophen, or ibuprofen to relieve pain, and says therapies like physical therapy, facial massage, or acupuncture may help with facial nerve function and pain relief.
COVID-19 vaccine and Bell's palsy: Is there a link?
None has been established. "I cannot make a direct connection with the vaccine and suspect this is a coincidence," Dr. Hinman says. "The normal incidence of Bell's palsy is roughly 20 people out of 100,000. The Pfizer study examined 38,000 patients, so four cases would be within the normal observed incidence of Bell's palsy."
A similar issue arose decades ago, when a few isolated cases of people developing Bell's palsy after getting a flu vaccine were reported. However, no study has ever established a link between the the flu vaccine and Bell's palsy.
Should you be worried about the new vaccine causing Bell's palsy? Probably not, since no link has been established. The small number of study subjects known to have developed it dwarfs the hundreds of thousands of people enrolled in the study trials, and as Dr. Hinman says, it may simply be a coincidence.
