Facial Twitching and A number of Sclerosis
Signs of MS Facial Twitching
It could begin as one thing we’re all acquainted with: tiny spasms round your eyelid.
“While you’re drained or careworn 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 might 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 focuses on MS on the Mayo Clinic.
Normally, 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.
“Folks 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.”
Completely 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 instances, it is perhaps an indication of a bigger problem associated to MS, together with:
Steady facial myokymia: This will really feel form 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 widespread in individuals who have MS. They usually’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.
Robust facial spasms might drive your eyelid closed or pull your mouth to at least one facet. You might really feel loads of tightness, Tobin says. Sooner or later, all of the muscle tissues on one facet 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 hardly 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’ll be able to’t eat. You’ll be able to’t discuss.”
What Causes MS Facial Twitching?
When you have got 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 muscle tissues the best way they need to.
Most individuals with MS facial twitching have a lesion in a sure a part of the brainstem referred to as the pons. Vital nerves go out and in of this bony canal. Medical doctors usually discover harm to the seventh cranial nerve, higher often known as the facial nerve.
Just like the identify suggests, your facial nerve controls your facial muscle tissues. (It additionally performs an element in how a few of your style buds work.)
It’s unclear precisely how MS lesions trigger facial twitching. We want extra analysis to search out out. However scientists have some theories, together with:
Ephaptic transmission: Nerve impulses inform your physique easy methods to transfer. However an absence of myelin could make your nerves glitchy. And when you have got 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 is perhaps acquainted with:
- 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 well 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 assume 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.
How Do You Diagnose MS Facial Twitching?
Not like different MS signs, steady facial myokymia and hemifacial spasm might not be an indication of a brand new lesion.
Nonetheless, your physician will need some new photos 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 may additionally get a particular nerve check. That is referred to as an electromyography (EMG). It’ll measure the timing of your muscle spasms. It is a good technique to inform the distinction between facial myokymia (quick spasms) and hemifacial spasm (extended spasms).
Your physician might order blood work or extra exams to rule out different well being circumstances. You’ll be able to have facial twitching for a lot of causes unrelated to MS, together with irritation or an infection.
Your facial twitches is perhaps idiopathic. Meaning “there’s no actual connection” to any medical problem, Stoll says.
Therapy for MS Facial Twitching
You might not must 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 folks might have these spasms for the remainder of their life.
The excellent news is you may get assist on your signs regardless of how quick or lengthy they final.
Therapy for MS facial twitching consists of:
Botox: Botulinum toxin can briefly paralyze facial muscle tissues. That’s the way it removes wrinkles. Nevertheless it’s additionally the simplest technique to cease critical facial twitches.
Botox will help folks 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 frequently treats hemifacial spasm. They’ll assist you determine when it’s protected to start out and cease remedy.
Different drugs: Your physician might have you ever strive different drug therapies. For gentle facial twitching, which may embrace
Life-style modifications: MS facial twitching isn’t your fault. “Nevertheless it’s extra prone to reappear with stress and fatigue,” Stoll says.

Random eyelid twitches are normally nothing to fret about.
However examine in together with your neurologist if different facial muscle 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 normally goes away in some unspecified time in the future. And when that occurs, chances are you’ll surprise: Will it come again?
“That’s a great query. I don’t assume we actually know,” Tobin says. “But when it’s gone for per week or two, then it’s most likely gone.”
