Most concussion headaches improve on their own within a few weeks, but the right combination of rest, light activity, pain management, and environmental changes can speed up relief and prevent the headache from becoming a longer-term problem. About 76% of people with a mild traumatic brain injury still report headaches at the one-month mark, so knowing how to manage symptoms early makes a real difference.
Start With Rest, Then Move
The outdated advice of lying in a dark room for days has been replaced by a more balanced approach. For the first one to two days, limit screen time and avoid activities that are physically or mentally demanding. Rest when you need to, but don’t isolate yourself in darkness all day.
After those first 48 hours, light aerobic activity like walking is not only safe but actually helps recovery. The current guidance from the 2023 Amsterdam Consensus Statement, endorsed by the American Academy of Pediatrics, is that light aerobic exercise can begin as early as two days after a concussion without needing medical clearance first. A brief, mild uptick in symptoms during activity (no more than a 2-point increase on a 0-to-10 scale, lasting less than an hour) is considered normal and does not delay healing. If symptoms get noticeably worse, scale back temporarily and try again the next day.
Over-the-Counter Pain Relief
Acetaminophen (Tylenol) is the most commonly recommended option for concussion headaches. A typical dose is 500 mg every four hours as needed, though you should follow whatever your provider recommends for your situation.
The critical rule with any pain reliever is to avoid using it too frequently. Taking headache medication more than two days per week can lead to medication overuse headache, a rebound cycle where the drugs themselves start triggering pain. For simple pain relievers like acetaminophen, this threshold sits at roughly 15 days per month. For combination pain relievers, it’s 10 days per month. Staying well under these limits keeps your recovery on track.
Adjust Your Environment
Light sensitivity is one of the most common triggers for concussion headaches, and not all light is equally problematic. Fluorescent lighting tends to be the worst offender. Fluorescent bulbs produce an invisible flicker that the brain can still detect, and they emit a large amount of blue-spectrum light, which is the wavelength most uncomfortable for people with post-concussion photophobia. If you work or study under fluorescent lights, switching to incandescent or LED bulbs with a warm color temperature can make a meaningful difference.
Anti-glare covers on screens and polarized lenses can help when you need to use devices. Specialized tinted lenses (FL-41 lenses) filter out light at the 480-nanometer wavelength, which is the specific band that activates the light-sensitive cells most involved in headache and photophobia. These are available as prescription or clip-on lenses. One important note: wearing sunglasses indoors is tempting but counterproductive. It forces your eyes to adapt to darkness, which makes the sensitivity worse over time rather than better.
Neck-Focused Physical Therapy
Many concussion headaches aren’t purely a brain problem. The same blow that rattled your brain likely also jarred your neck, and irritated cervical joints and tight muscles in the neck and upper back can generate headaches of their own. These cervicogenic headaches often overlap with the concussion itself, and treating the neck component can significantly reduce overall headache intensity.
A combination of hands-on cervical mobilization and strengthening exercises for the neck and shoulder blade muscles has the strongest evidence for this type of headache. In studies, people doing targeted neck and upper-back strengthening exercises twice daily saw significant improvements in headache frequency, headache intensity, and neck pain by seven weeks. Those improvements held up at 12 months. Adding manual joint mobilization from a physical therapist made results even better across all measures.
The Amsterdam consensus recommends starting cervical and vestibular rehabilitation if you still have headaches, neck pain, or dizziness beyond 10 days post-injury. If dizziness is a prominent symptom, vestibular rehab may help after just five days.
When Headaches Last More Than a Month
If your headaches haven’t improved after about 30 days, the consensus recommendation is active rehabilitation and collaborative care, meaning a coordinated approach that might include a physician, physical therapist, and psychologist working together. For headaches occurring more than one to two days per week that are interfering with your daily life, preventive prescription medications may be considered starting around four to six weeks post-injury.
The specific medication depends on what your headaches look and feel like. If they resemble migraines (throbbing, one-sided, with nausea or light sensitivity), options like amitriptyline have shown promising results. In one study of 44 patients, 82% experienced at least a 50% reduction in headache days after starting it about a month post-injury and continuing for a median of four months. Sedation was the main side effect, reported by about a third of participants. Topiramate is another option; in one group, 75% of patients with migraine-like post-concussion headaches reported reduced headache frequency. Propranolol, a beta-blocker, showed a 50% reduction in headache frequency for about half the patients who tried it.
Headaches that persist beyond three months are classified as persistent post-traumatic headache. Roughly 32% of people with a mild brain injury still have headaches at three months, and studies suggest that 49% to 58% may continue experiencing them at the one-year mark. This does not mean they’re untreatable; it means the treatment approach shifts from watchful recovery to active, targeted management.
Returning to School and Work
Screen time, reading, and mental concentration can all aggravate concussion headaches, which makes returning to school or desk work tricky. The key principle is the same as with physical activity: gradual reintroduction with a tolerance for mild, short-lived symptom increases. If a task pushes your headache up slightly but it settles back down within an hour, that level of exertion is fine.
Practical accommodations that help include reduced screen brightness, more frequent breaks, shorter assignments or workdays, and testing in a quieter environment with extended time. These aren’t about avoiding all discomfort. They’re about keeping cognitive demands within a window that doesn’t spiral your symptoms.
Signs That Need Emergency Attention
Most concussion headaches are manageable at home, but certain patterns signal something more serious. Go to the emergency department or call 911 if you notice any of the following after a head injury:
- A headache that keeps getting worse and won’t go away
- Repeated vomiting
- Seizures or convulsions
- Increasing confusion, agitation, or unusual behavior
- Slurred speech, weakness, numbness, or poor coordination
- One pupil noticeably larger than the other, or double vision
- Inability to wake up or stay awake
- Inability to recognize familiar people or places
These can indicate bleeding or swelling in the brain, which requires immediate evaluation. A concussion headache that is steady or slowly improving is expected. One that progressively worsens over hours is not.
