One side of my face droops
See a doctor about this one
See a doctor about this one. It is a symptom that needs a cause found, and no remedy on this site is a substitute for that.
You look in the mirror and one side of your face hangs down. Your eyelid may not shut all the way. One corner of your mouth may sag.
Food or drink may leak out of that side. Your smile may look crooked. The side may feel stiff, heavy, or numb, even though touch still feels normal.
This happens when the nerve that runs to your face stops sending signals. The muscles on that side go slack. Bell's palsy is one common cause, but it is not the only one.
A new face droop always needs to be checked right away. A stroke can look much the same in the first hour. Only an exam can sort them out safely.
When to see someone
Call 911 now for any new face droop. Say the words "face droop" on the phone. Do not drive yourself.
Call 911 right away if you also have slurred speech, a weak arm or leg, a bad headache, or sudden blurred sight. These point to stroke. Minutes count.
Go in the same day for blisters or a rash in or around the ear. Go the same day for bad ear pain, fever, pus from the ear, spinning, or new hearing loss.
Go the same day if your eye will not close. A dry eye can scar fast. You need drops and a way to keep it shut at night.
See a doctor soon if the droop came on slowly over weeks, keeps getting worse, or hits both sides. Same if it came after a tick bite or a blow to the head. Go back if you see no change at all after three to four weeks.
Why it happens
One nerve runs to each side of your face. It tells your brow, your eyelid, your cheek, and your lip to move. It also carries taste from the front of your tongue.
That nerve passes through a narrow bony tunnel near your ear. If it swells, the tunnel squeezes it. The signal gets weak or stops, and the muscles go limp.
In Bell's palsy, doctors think a common virus wakes up and irritates the nerve. The swelling does the damage, not the virus itself. That is why the droop builds over hours or a day or two.
Bell's palsy hits one side only. It usually takes the whole side, brow and all. Most people start to improve on their own within a few weeks.
What else it could be
Stroke is the cause to rule out first. In many strokes, the forehead on the droopy side still wrinkles when you raise your brows, because the brain feeds that muscle from both sides.
A stroke also often brings a weak arm, slurred speech, or sudden trouble seeing. This is a 911 call, not a wait-and-see.
Bell's palsy usually takes the whole half of the face. The brow will not lift and the eye will not shut. It often comes with ear ache, a odd taste, or sound feeling too loud in that ear.
Ramsay Hunt syndrome is shingles of the face nerve. It brings a painful, blistery rash in or around the ear, on the ear canal, or on the roof of the mouth.
It can also cause spinning, ringing, or hearing loss. It needs antiviral medicine fast, so do not treat it as plain Bell's palsy.
Lyme disease is a common cause in tick country, mostly in warm months. It can droop both sides of the face, which Bell's palsy rarely does. Look for a spreading rash, fever, or aching joints in the weeks before.
Ear infection can spread to the nerve. Think of this with fever, deep ear pain, pus from the ear, or swelling behind the ear. It is more common in kids.
Injury is another cause. A blow to the head or ear, a skull fracture, or recent surgery near the ear or jaw can bruise or cut the nerve.
A droop that creeps in over weeks or months is a different story. Slow weakness, a lump near the ear or jaw, or weakness that keeps getting worse can mean a growth pressing on the nerve. That needs scans, not home care.
One more check: if only your lower lip sags and your eye and brow work fine, the cause may be a small branch of the nerve, dental numbing, or a jaw problem. Still get it looked at the same day.
How to read the grades below
The options below come from our page on Bell's Palsy. Each one carries two labels.
The first label is the evidence grade. A means strong trials in people, B means smaller or mixed studies, and C means early or limited findings. D means lab work only, and “insufficient” means the research cannot settle it yet.
The second label is the traditional tier. T3 means long use in more than one tradition, T2 means long use in one, and T1 means known use. T0 means no such record.
These grades come from research on Bell's Palsy, the parent Health Topic, not on one side of my face droops.
A grade tells you how strong the research is, not how well something will work for you. Talk to a doctor or pharmacist before you start anything, above all if you take other medicines.
What to try first
Get checked first, today. If it is Bell's palsy, steroid pills work best when they start in the first three days. Waiting can cost you that window.
Protect the eye while you wait. If the lid will not shut, the eye can dry out and get scratched. Ask your doctor about drops by day, ointment at night, taping the lid shut for sleep, and sunglasses outdoors.
Then talk over the options below with your doctor. None of them can promise a result. Use them next to your medical care, not in place of it.
Moxibustion has evidence grade B and traditional tier T3. Grade B means some human trials back it, but the proof is not airtight. T3 means it has deep roots in East Asian practice.
Methylcobalamin (B12 Active Form) has evidence grade B and traditional tier T0. It is a form of vitamin B12 used to support nerves. T0 means it is a modern product with no folk history behind it.
Acupuncture has evidence grade insufficient and traditional tier T3. That means the trials so far are too few or too weak to settle it. Long use by tradition is not the same as proof.
Physical Therapy has evidence grade insufficient and traditional tier T0. Face exercises, massage, and mirror work are often offered. The trial proof is thin, but a trained therapist can coach you and spot bad movement habits early.
How long it takes
Most people with Bell's palsy notice the first small gains in two to three weeks. Many get back to normal, or close to it, by three to six months. Some keep a bit of weakness or stiffness after that.
Speed matters most on day one. Steroids help most when they start within 72 hours of the droop.
If you add any option above, give it weeks, not days. Set a check-in with your doctor at about four weeks. If nothing at all has changed by then, ask for more tests.
