Concussion headaches are one of the most common symptoms after a head injury, and the safest way to treat them starts with rest, hydration, and avoiding any medication that could mask worsening symptoms. The first step is always to get a medical evaluation to rule out a more serious brain injury. After that, the safest treatments include limited use of acetaminophen (Tylenol) under a doctor’s guidance, strict rest from screens and mental activity, and gradual return to normal routines only when symptoms allow. No treatment is truly safe without first understanding the severity of your injury.
What Actually Causes Concussion Headaches?
A concussion is a mild traumatic brain injury. The brain is soft tissue inside a hard skull. When you hit your head, the brain moves and stretches. This damages nerve cells and causes a chemical imbalance.
The headache you feel is not like a tension headache or migraine from stress. It is a direct result of the brain’s energy systems being disrupted. The brain temporarily cannot manage blood flow and energy use the way it should.
Research published in the Journal of Head Trauma Rehabilitation shows that these headaches are caused by a combination of inflammation, reduced blood flow to certain areas, and over-excitation of nerve pathways. This is why typical headache treatments often do not work or can even make things worse.
The most important thing to understand is that your brain needs energy to heal. Pushing through a headache or taking strong pain relievers can interfere with that healing process.
How To Get Rid Of Concussion Headaches Safe Treatments
The safest treatment protocol for concussion headaches follows a structured approach. It is not about finding one magic pill.
Step one: Complete cognitive and physical rest for 24-48 hours. This means no screens, no reading, no loud noises, no bright lights, and no physical exertion. Even conversations can be too much in the first day. This gives your brain a chance to reset its energy systems.
Step two: Use acetaminophen (Tylenol) only if needed and only after a doctor approves it. Acetaminophen is the safest over-the-counter option because it does not thin the blood or increase bleeding risk. Do not use ibuprofen (Advil), naproxen (Aleve), or aspirin for at least 48 hours after a concussion unless a doctor specifically says it is safe. These drugs can increase the risk of bleeding inside the brain.
Step three: Manage your environment. Dim lights. Reduce noise. Take breaks from any activity that makes the headache worse. The CDC recommends a “symptom-limited” approach — if an activity makes your headache worse by 2 or 3 points on a 0-10 scale, stop and rest.
Step four: Stay hydrated and eat small, regular meals. Dehydration and low blood sugar can make concussion headaches worse. Water and bland foods like crackers or toast are best in the first few days.
Step five: Gradual return to normal activity. The American Academy of Neurology recommends a stepwise return. Start with 5-10 minutes of light activity (like walking) and see how your headache responds. If it gets worse, rest more. If it stays the same or improves, you can slowly increase activity over days or weeks.
| Symptom Level | Recommended Action | What to Avoid |
|---|---|---|
| Mild headache, no other symptoms | Light activity, acetaminophen if needed | Screens, loud environments |
| Moderate headache, some sensitivity to light or noise | Rest in dark quiet room, no medication unless prescribed | Reading, driving, work |
| Severe headache, vomiting, confusion, or vision changes | Go to emergency room immediately | Do not wait or take any medication |
What Treatments Should You Avoid After a Concussion?
Many common headache remedies are dangerous after a concussion. This is where most people make mistakes.
Never take ibuprofen (Advil, Motrin) or aspirin for the first 48 hours. These are non-steroidal anti-inflammatory drugs (NSAIDs). They thin the blood and can mask symptoms of a bleed. The Centers for Disease Control and Prevention warns against them in the acute phase.
Avoid opioid painkillers. Some doctors may prescribe them for severe pain, but research in the journal Neurology shows opioids can slow concussion recovery and increase the risk of long-term symptoms. They also cause drowsiness, which makes it harder to monitor your condition.
Do not use cannabis or CBD for headache relief. As of 2026, there is no clinical evidence that cannabis helps concussion headaches. Some studies suggest it may actually worsen cognitive symptoms and delay recovery.
Avoid caffeine in the first week. Caffeine changes blood flow in the brain. For some people it can trigger rebound headaches. For others it can mask symptoms and cause you to overdo activity.
Do not “sleep it off” without being checked. It is a myth that you should not sleep after a concussion. But someone should check on you every 2-3 hours for the first 24 hours to make sure you can be woken up normally. If you cannot be woken, that is a medical emergency.
How Long Do Concussion Headaches Last?
Most concussion headaches resolve within 7 to 10 days. Research from the University of Pittsburgh Medical Center shows that about 80% of adults recover fully within two weeks.
But some people have headaches that last much longer. This is called post-concussion syndrome. It affects roughly 10-20% of people with concussions. Women and people with a history of migraines or anxiety are at higher risk.
If your headache lasts more than two weeks, you need to see a specialist. A neurologist or a sports medicine doctor who treats concussions can help. They may recommend physical therapy for the neck (because whiplash often happens with concussions), vision therapy, or specific medications that are safe for long-term use.
The key sign that recovery is going well is that your headache gets better over time, even if slowly. If your headache suddenly gets worse days after the injury, or if new symptoms like vomiting or confusion appear, go to the emergency room.
What Does Research Say About Natural Remedies for Concussion Headaches?
Some people report that natural treatments help, but strong evidence is limited for most of them.
Magnesium supplements are sometimes suggested because magnesium helps regulate nerve function. Some studies suggest it may help with migraine-type headaches, but there is no specific research on concussion headaches. If you try it, keep the dose under 400 mg per day to avoid digestive issues.
Omega-3 fatty acids (fish oil) have been studied for brain recovery after injury. Animal studies show promise, but human studies are still inconclusive. The National Institutes of Health notes that high doses can thin the blood, so check with a doctor before taking them after a concussion.
Vitamin B2 (riboflavin) has some evidence for migraine prevention, but not specifically for concussion headaches. The doses used in studies (400 mg daily) are much higher than what is in a typical multivitamin.
Peppermint or lavender essential oils are widely claimed to help headaches. There is no clinical evidence that they help concussion headaches specifically. Some people find the smell soothing, which may help them relax. That is not the same as treating the injury.
Acupuncture has some evidence for chronic pain conditions, but not for acute concussion headaches. The American Academy of Neurology lists it as a treatment option only for persistent post-concussion syndrome, not for the first weeks after injury.
The honest answer is that no natural remedy has been proven to speed up brain healing after a concussion. The safest approach is rest, time, and careful symptom management.
When Should You See a Doctor for a Concussion Headache?
You should see a doctor within 24 hours of any head injury that causes a headache, even if you think it is mild. This is not optional. A healthcare professional needs to assess you for signs of a more serious injury.
Go to the emergency room immediately if you have any of these symptoms:
- Headache that gets worse over time
- Vomiting more than once
- Slurred speech
- Weakness or numbness in arms or legs
- Seizures
- One pupil larger than the other
- Confusion or trouble recognizing people
- Loss of consciousness (even briefly)
For ongoing headaches that last more than two weeks, see a concussion specialist. Many major hospitals now have concussion clinics. They can do specialized testing to find out if your headache is coming from the brain injury itself, from neck strain, or from other factors like sleep disruption.
Do not try to treat a concussion headache on your own for more than a few days. The brain is complex. What works for one person may not work for another. A specialist can help you find the right combination of rest, activity, and safe medications for your specific situation.
Frequently Asked Questions
Can I take ibuprofen for a concussion headache?
Avoid ibuprofen for the first 48 hours after a concussion because it increases bleeding risk. After that, only take it if a doctor approves it for your specific case.
How long should I rest after a concussion before treating the headache?
Complete rest for 24-48 hours is recommended before starting any active treatment. Your brain needs this time to begin healing on its own.
Is it safe to sleep with a concussion headache?
Yes, sleep is safe and actually helps the brain heal. Have someone check on you every 2-3 hours to ensure you can be woken normally.
What is the fastest way to get rid of a concussion headache?
The fastest safe approach is strict rest in a dark quiet room, hydration, and acetaminophen if your doctor approves it. There is no quick fix that is also safe.
