Signs of MS Facial Twitching
It could begin as one thing we’re all accustomed to: tiny spasms round your eyelid.
“Whenever you’re drained or burdened and also you get fluttering beneath 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 could unfold. It’d go down your cheek to your mouth or jawline. And it occurs extra usually. “It’s occurring a number of instances a day,” says Oliver Tobin, MB, a neurologist who makes a speciality of MS on the Mayo Clinic.
Often, MS facial twitching impacts one aspect of your face at a time. And you could discover different facial signs first, like numbness, tingling, weak point, or different bizarre sensations.
“Folks will often 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.”
Completely different Kinds of MS Facial Twitching
Even for individuals who have MS, an occasional eyelid tremble, by itself, often has nothing to do with the illness. However in some circumstances, it could be an indication of a bigger subject associated to MS, together with:
Steady facial myokymia: This may really feel sort of like an eyelid twitch (myokymia). However you’ll get ongoing spasms in different areas, akin to your brow, cheek, mouth, and chin.
These twinges are comparatively frequent in individuals who have MS. They usually’re often 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 could power your eyelid closed or pull your mouth to at least one aspect. You might really feel a variety of tightness, Tobin says. In some unspecified time in the future, all of the muscular tissues on one aspect of your face could also be concerned. It could appear to be you’re having a seizure.
It’s uncommon for MS to trigger hemifacial spasm. Stoll rarely sees it in her observe. 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 possibly can’t eat. You possibly can’t discuss.”
What Causes MS Facial Twitching?
When you’ve MS, your immune system breaks down myelin. That’s the protecting cowl round your nerves. With out this insulation, it’s laborious for alerts to journey out of your mind to your muscular tissues 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. Medical doctors usually discover injury to the seventh cranial nerve, higher often known as the facial nerve.
Just like the identify suggests, your facial nerve controls your facial muscular tissues. (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 the best way to transfer. However a scarcity of myelin could make your nerves glitchy. And when you’ve two broken (demyelinated) nerves proper subsequent to one another, {the electrical} sign from one can set off the opposite.
“It’s primarily like a leaky present,” Tobin says.
Listed below are some examples of ephaptic transmission that you just could be accustomed to:
- Lhermitte’s signal: You bend your neck and get a buzzing sensation down your physique. It could be an indication of MS, however it may possibly 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 often final 60 to 90 seconds.
Nerve hyperexcitability: Your facial nerve could hearth greater than it ought to. Some scientists assume hyperexcitability from different areas could trigger MS facial twitching even when you don’t have a visual lesion within the pons of your mind stem.
How Do You Diagnose MS Facial Twitching?
Not like different MS signs, steady facial myokymia and hemifacial spasm is probably not an indication of a brand new lesion.
Nonetheless, your physician will need some new footage of your mind to make certain. 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 may additionally 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 option to inform the distinction between facial myokymia (quick spasms) and hemifacial spasm (extended spasms).
Your physician could order blood work or extra exams to rule out different well being situations. You possibly can have facial twitching for a lot of causes unrelated to MS, together with irritation or an infection.
Your facial twitches could be idiopathic. Meaning “there’s no actual connection” to any medical subject, Stoll says.

You might not have to do something besides wait. Facial twitching usually resolves by itself after just a few weeks or months. That’s very true for facial myokymia, Tobin says.
MS-related hemifacial spasm additionally tends to ease over time. However it might take years. And a few individuals could have these spasms for the remainder of their life.
The excellent news is you will get assist in your signs regardless of how quick or lengthy they final.
Therapy for MS facial twitching consists of:
Botox: Botulinum toxin can briefly paralyze facial muscular tissues. That’s the way it removes wrinkles. Nevertheless it’s additionally the simplest option to cease severe facial twitches.
Botox can assist individuals with hemifacial spasm “get their lives again,” Stoll says.
You’ll usually want photographs each 3 months till your spasms cease. Ask your physician to refer you to a neurologist who often treats hemifacial spasm. They’ll assist you determine when it’s protected to begin and cease therapy.
Different drugs: Your physician could have you ever strive different drug remedies. For gentle facial twitching, that may embrace
Life-style adjustments: MS facial twitching isn’t your fault. “Nevertheless it’s extra more likely to reappear with stress and fatigue,” Stoll says.

However verify in together with your neurologist if different facial muscular tissues begin to spasm. Name them instantly in case your twitches are new and final for greater than 24 hours. “That’s true for any symptom from a number of sclerosis,” Stoll says.
MS facial twitching often goes away in some unspecified time in the future. And when that occurs, you could marvel: Will it come again?
“That’s query. I don’t assume we actually know,” Tobin says. “But when it’s gone for every week or two, then it’s most likely gone.”
