Signs of MS Facial Twitching
It could begin as one thing we’re all aware of: tiny spasms round your eyelid.
“If 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 Medication. And for most individuals, that’s so far as it goes.
However when this twitching is from multiple sclerosis (MS), this facial twitching could 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.
Normally, MS facial twitching impacts one facet of your face at a time. And it’s possible you’ll discover different facial signs first, like numbness, tingling, weak spot, 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 Sorts 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 may be an indication of a bigger difficulty associated to MS, together with:
Steady facial myokymia: This could really feel type of like an eyelid twitch (myokymia). However you’ll get ongoing spasms in different areas, akin to your brow, cheek, mouth, and chin.

It’s unclear precisely how MS lesions trigger facial twitching. We want extra analysis to seek out out. However scientists have some theories, together with:
Ephaptic transmission: Nerve impulses inform your physique the right way to transfer. However an absence 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 basically like a leaky present,” Tobin says.
Listed here are some examples of ephaptic transmission that you simply may be aware of:
