Can Bell’s Palsy Come Back? Recurrence Rates, Causes and How to Lower Your Risk
Can facial palsy happen twice? Bell’s palsy recurrence rates, who is most at risk, when a recurrence needs further tests, and how to lower your risk and handle a second episode.
After recovering from facial palsy, many people worry: “Can it come back?” The reassuring answer is that most people never have a second episode. But knowing the facts helps you act fast if it does.
How often does Bell’s palsy recur?
Studies suggest Bell’s palsy recurs in about 7–15% of people — so roughly 85–93% never experience it again.
- A recurrence can affect the same side or the other side.
- It may happen months or years after the first episode.
Who is more likely to have a recurrence?
| Factor | Note |
|---|---|
| Diabetes | One of the factors most associated with recurrence |
| Family history | Some families are more prone, possibly for genetic or anatomical reasons such as a narrow nerve canal |
| High blood pressure | A general risk factor for Bell’s palsy |
| Weakened immunity | May make viral reactivation easier — see what causes Bell’s palsy |
When does recurrence need further tests?
Bell’s palsy is a diagnosis made after other causes are ruled out. Your doctor is more likely to order detailed tests if there is:
- Recurrence on the same side.
- Palsy that develops gradually over weeks rather than suddenly.
- No improvement at all after 3–4 months.
- Other symptoms, such as hearing loss, a lump near the ear or numbness elsewhere.
Tests may include an MRI scan, blood sugar and other blood tests, to rule out rare causes such as tumours or inflammatory diseases.
What to do if palsy returns
Treat it like a new episode:
- Rule out stroke first — see Bell’s palsy vs stroke.
- See a doctor within 72 hours to start the right treatment — see our treatment guide.
- Protect your eye straight away — see our eye care guide.
- Resume your exercises once your doctor agrees — your experience from last time will help.
Can recurrence be prevented?
There’s no guaranteed way, but you can lower general risk factors:
- Control blood sugar and blood pressure, with regular check-ups.
- Sleep well and manage chronic stress.
- Eat a balanced diet that supports nerve health — see nutrition for facial nerve recovery.
- Treat colds and ear infections properly.
- Ask about the shingles vaccine after 50 if your doctor recommends it.
The emotional side

Frequently asked questions
How often does Bell’s palsy come back?
Studies suggest Bell’s palsy recurs in roughly 7–15% of people, which means the large majority never have a second episode.
Is a second episode worse than the first?
Not necessarily. Many people recover well from a second episode, though some studies suggest recovery may be less complete when it recurs on the same side.
Does recurrence mean a tumour?
In the vast majority of cases, no. But same-side recurrence, or palsy that starts gradually and doesn’t improve, will prompt your doctor to order imaging to rule out rare causes.
