How do I know it is not a stroke?
The forehead. In Bell's palsy you cannot wrinkle the forehead or raise the eyebrow on the affected side.
If the forehead still moves but the lower face has dropped, treat it as a stroke and call 999. The same applies to any limb weakness, difficulty speaking, or instantaneous onset.
How quickly do I need to be seen?
Within 72 hours. Steroids work considerably better when started early, and the benefit falls away after that window.
Do not wait to see whether it settles.
Will my face go back to normal?
Most people recover fully. Improvement typically begins within two to three weeks and continues over three to six months.
A minority have some lasting weakness, which is why early treatment and eye protection matter.
Why does my eye need so much attention?
Because it cannot close, so it dries out — and a dry cornea can ulcerate and scar.
Drops by day, ointment and taping at night. It is the single most important piece of self-care, and it is frequently under-emphasised.
What is Ramsay Hunt syndrome?
Shingles affecting the facial nerve, causing facial weakness alongside a painful blistering rash in or around the ear — sometimes in the mouth.
It needs different, higher-dose antiviral treatment and has a poorer outlook if missed, so mention any rash, ear pain or hearing change.
Could this be Lyme disease?
Worth raising if you have had a tick bite, a spreading circular rash, or if both sides of your face are affected.
Bilateral facial weakness is rarely Bell's palsy and warrants a different workup.
Can it come back?
Recurrence is uncommon. Where it does recur, or affects the same side twice, that warrants further investigation rather than simply repeating treatment.
Does stress cause it?
There is no good evidence that it does. The most widely accepted explanation is reactivation of a virus affecting the nerve, and in most cases no trigger is ever identified.
