If you develop Bell’s palsy, the most important step is starting oral steroids within 72 hours of symptom onset. About 71% of people recover full facial function overall, but that number climbs to 72% with steroid treatment compared to 57% without it. Beyond medication, protecting your eye, managing pain, and beginning facial exercises at the right time all play roles in a smoother recovery.
Rule Out a Stroke First
Bell’s palsy and stroke both cause facial drooping, but they affect the face differently. Bell’s palsy paralyzes the entire half of your face, including the forehead. A stroke typically spares the forehead and only weakens the lower face. If you can raise both eyebrows normally but one side of your lower face is drooping, that pattern is more consistent with a stroke and warrants an immediate call to emergency services.
Bell’s palsy also comes with its own set of accompanying symptoms that strokes don’t typically cause: pain behind the ear, heightened sensitivity to sounds on the affected side, changes in taste, and excessive tearing or dryness in one eye. If you notice these alongside full one-sided facial weakness, Bell’s palsy is the more likely explanation, but getting evaluated quickly still matters because of the treatment window.
Start Steroids Within 72 Hours
Oral corticosteroids are the cornerstone treatment. The standard adult regimen is a high dose for the first four days, followed by a tapering schedule over the next seven days. The best outcomes are linked to starting this medication within three days of symptom onset. In a large trial of 839 people with moderate to severe weakness, 72% of those who received steroids had full facial recovery at 12 months, compared to 57% on placebo. That 15 percentage point difference is significant enough to make early treatment worth prioritizing.
Antiviral medications are sometimes prescribed alongside steroids, based on the theory that a reactivated herpes virus triggers the nerve inflammation. However, the evidence for adding antivirals is weak. Guidelines from the American Academy of Neurology note that antivirals combined with steroids do not improve the chance of recovery by more than 7%, and even that modest benefit hasn’t been firmly established. Your doctor may offer them, but steroids alone produce the most reliably favorable outcomes.
Protect Your Eye Immediately
When the muscles on one side of your face stop working, you lose the ability to fully close that eye. This leaves your cornea exposed to drying, dust, and accidental scratches. Corneal damage is one of the most preventable complications of Bell’s palsy, so eye care should start right away.
During the day, use lubricating eye drops frequently and wear glasses or goggles to shield your eye from debris and wind. At night, switch to a thicker eye ointment (available over the counter at pharmacies) because drops evaporate while you sleep. Tape an eye patch over the affected eye before bed, or use medical tape to gently hold the eyelid closed. This overnight protection is especially important since you won’t notice dryness or irritation while sleeping.
Manage Pain and Discomfort
Many people with Bell’s palsy experience aching pain behind the ear on the affected side, sometimes starting a day or two before the facial weakness appears. Over-the-counter pain relievers can help with this. Applying a warm, moist cloth to the side of your face several times a day can also ease discomfort and reduce the feeling of stiffness in the paralyzed muscles. The pain typically fades within the first week or two as the acute inflammation settles.
When and How to Start Facial Exercises
Facial neuromuscular retraining is the most widely studied physical therapy approach for Bell’s palsy. Some studies begin exercises as early as 48 hours after onset, while others start within the first five to ten days. Your timeline will depend on how much movement you have and your clinician’s assessment, but the general principle is to begin gentle work early rather than waiting weeks.
The most common technique involves practicing facial movements in front of a mirror. You watch yourself attempt expressions like smiling, raising your eyebrows, and puckering your lips, using the visual feedback to train the nerve-muscle connection. Sessions are typically short (around 30 minutes of home practice daily) and focus on quality of movement rather than forceful repetition. The goal is retraining the nerve pathways, not building muscle strength through heavy effort.
Standard rehabilitation programs combine several elements: gentle massage of the face, stretching of tight facial muscles, neuromuscular re-education with mirror feedback, and postural exercises. Some clinics also use electromyographic biofeedback, where sensors on your face give you real-time information about which muscles are activating, helping you isolate the correct movements. A protocol called mirror book therapy, which uses a reflected image of your unaffected side to create the visual illusion of symmetric movement, has also shown promise in small studies.
What Recovery Looks Like
Bell’s palsy has a genuinely encouraging prognosis. About 85% of people see meaningful improvement within three weeks. The remaining 15% take longer, typically recovering over three to five months. People with partial paralysis at the start do particularly well: 94% recover completely. Those with complete paralysis still have a 61% chance of full recovery.
Recovery isn’t always perfectly linear. You may notice certain movements returning before others, or one part of your face recovering faster. The muscles around the mouth often take longer than those around the eye. Most people notice the first signs of returning movement within two to three weeks, though subtle improvements can continue for several months.
If Recovery Is Incomplete
About 29% of people are left with some degree of permanent residual effects. The most common long-term complication is synkinesis, an involuntary movement that happens when you’re trying to move a different part of your face. For example, your eye might close involuntarily when you smile, or your mouth might twitch when you try to blink. This happens because regenerating nerve fibers sometimes reconnect to the wrong muscles. Around 16% of people develop synkinesis or hemifacial spasm after Bell’s palsy, and 17% experience some degree of facial contracture (persistent tightness).
Synkinesis is manageable. The most effective approach is biofeedback therapy, where you practice specific movements in front of a mirror while consciously suppressing the unwanted motion. For instance, if your eye closes when you smile, you’d practice smiling slowly while focusing on keeping your eye open, using the mirror to monitor your progress. With repetition, the brain can learn to inhibit the misfired signals. Targeted injections to temporarily weaken the overactive muscles are another option for more disruptive cases, and these are often combined with ongoing rehabilitation to retrain movement patterns.
Complementary Approaches
Acupuncture is one of the more commonly explored complementary therapies for Bell’s palsy. A meta-analysis of five studies found that acupuncture combined with vitamin B12 reduced the rate of incomplete recovery compared to acupuncture alone, with the incomplete recovery rate dropping from about 63% to 45% in the combined group. Vitamin B12 has a known role in supporting peripheral nerve repair, and one randomized trial found that patients treated with B12 (alone or with steroids) recovered faster than those on steroids alone. These findings are suggestive but come from small studies, so B12 and acupuncture are best viewed as potential additions to standard steroid treatment rather than replacements for it.
