Signs of MS Facial Twitching
It might begin as one thing we’re all aware of: tiny spasms round your eyelid.
“Whenever you’re drained or confused and also you get fluttering underneath your eye or eyelid and it’s actually annoying,” says Sharon Stoll, DO, a neurologist and MS specialist with Yale Drugs. And for most individuals, that’s so far as it goes.
However when this twitching is from a number of sclerosis (MS), this facial twitching might unfold. It would go down your cheek to your mouth or jawline. And it occurs extra usually. “It’s occurring a number of occasions a day,” says Oliver Tobin, MB, a neurologist who focuses on MS on the Mayo Clinic.
Often, MS facial twitching impacts one facet of your face at a time. And chances are you’ll discover different facial signs first, like numbness, tingling, weak point, or different bizarre sensations.
“Individuals will normally say, ‘My face feels swollen, however I look within the mirror and it’s not swollen,’” Stoll says. “And the spasms will occur months later.”
Totally different Kinds of MS Facial Twitching
Even for individuals who have MS, an occasional eyelid tremble, by itself, normally has nothing to do with the illness. However in some circumstances, it is perhaps an indication of a bigger subject associated to MS, together with:
Steady facial myokymia: This may really feel form of like an eyelid twitch (myokymia). However you’ll get ongoing spasms in different areas, comparable to your brow, cheek, mouth, and chin.
These twinges are comparatively frequent in individuals who have MS. And so they’re normally short-lived and painless. However they are often uncomfortable. “It simply feels bizarre,” Tobin says.
Hemifacial spasm: In comparison with facial myokymia, these are longer-lasting contractions.
Sturdy facial spasms might pressure your eyelid closed or pull your mouth to 1 facet. Chances are you’ll really feel plenty of tightness, Tobin says. Sooner or later, all of the muscle groups on one facet of your face could also be concerned. It might appear like you’re having a seizure.
It’s uncommon for MS to trigger hemifacial spasm. Stoll hardly sees it in her follow. But when it occurs to you, it tends to be extra extreme and lifestyle-limiting than facial myokymia.
“Think about if half your face is spasming on a regular basis,” she says. “You may’t eat. You may’t discuss.”
What Causes MS Facial Twitching?
When you’ve gotten MS, your immune system breaks down myelin. That’s the protecting cowl round your nerves. With out this insulation, it’s laborious for indicators to journey out of your mind to your muscle groups the best way they need to.
Most individuals with MS facial twitching have a lesion in a sure a part of the brainstem known as the pons. Vital nerves go out and in of this bony canal. Docs usually discover harm to the seventh cranial nerve, higher often known as the facial nerve.
Just like the title suggests, your facial nerve controls your facial muscle groups. (It additionally performs a component in how a few of your style buds work.)
It’s unclear precisely how MS lesions trigger facial twitching. We’d like extra analysis to seek out out. However scientists have some theories, together with:
Ephaptic transmission: Nerve impulses inform your physique learn how to transfer. However an absence of myelin could make your nerves glitchy. And when you’ve gotten two broken (demyelinated) nerves proper subsequent to one another, {the electrical} sign from one can set off the opposite.
“It’s basically like a leaky present,” Tobin says.
Listed here are some examples of ephaptic transmission that you just is perhaps aware of:
- Lhermitte’s signal: You bend your neck and get a buzzing sensation down your physique. It might be an indication of MS, however it may occur to anybody.
- Tonic spasms: You go to face or transfer your physique and get painful muscle contractions in your arms or legs. These spasms normally final 60 to 90 seconds.
Nerve hyperexcitability: Your facial nerve might hearth greater than it ought to. Some scientists suppose hyperexcitability from different areas might trigger MS facial twitching even in case you don’t have a visual lesion within the pons of your mind stem.

Nonetheless, your physician will need some new footage of your mind to make sure. Up to date MRI scans can provide robust clues about whether or not your MS is well-controlled otherwise you’re having a relapse.
You might also get a particular nerve check. That is known as an electromyography (EMG). It’ll measure the timing of your muscle spasms. It is a good strategy to inform the distinction between facial myokymia (quick spasms) and hemifacial spasm (extended spasms).
Your physician might order blood work or further checks to rule out different well being circumstances. You may have facial twitching for a lot of causes unrelated to MS, together with irritation or an infection.
Your facial twitches is perhaps idiopathic. Which means “there’s no actual connection” to any medical subject, Stoll says.

MS-related hemifacial spasm additionally tends to ease over time. However it might take years. And a few folks might have these spasms for the remainder of their life.
The excellent news is you may get assist on your signs irrespective of how quick or lengthy they final.
Remedy for MS facial twitching contains:
