A concussion can trigger migraine attacks or migraine-like headaches, and people with a migraine history tend to have a higher chance of that pattern.
After a head hit, a headache can feel scary. It might be dull pressure, or pounding pain with nausea and light sensitivity that feels like migraine. Headache is common after concussion.
What Concussion-Related Headaches Can Feel Like
A concussion is a mild traumatic brain injury caused by a bump, blow, or jolt that makes the brain move inside the skull. You don’t need a blackout for it to count. Symptoms can start right away, or they can show up later the same day or the next day.
Some post-injury headaches feel like tension headaches: steady pressure, tight scalp, sore neck. Others match a migraine-style pattern: throbbing pain, nausea, light sensitivity, sound sensitivity, and worse pain with movement. A migraine pattern can happen even if you never used the word “migraine” before.
Can A Concussion Cause A Migraine? What To Know Right Away
Yes. A concussion can trigger a migraine attack, and it can also kick off a migraine-like headache pattern after the injury. Clinicians often call this post-traumatic headache, which means a headache that starts after head injury. Post-traumatic headache can look a lot like migraine.
The American Migraine Foundation explains that post-traumatic headache is often misunderstood because it overlaps with concussion symptoms, and many people report migraine-like features such as nausea, dizziness, trouble sleeping, and sensitivity to light and sound. It also notes that a prior migraine history can raise risk. American Migraine Foundation on concussion and post-traumatic headache spells out those patterns.
That overlap is why the label matters less than the pattern. If your headache acts like migraine, care often borrows from migraine treatment, plus concussion recovery steps.
Migraine After Concussion: Why It Happens
A head injury can stir up a few systems at once:
- Nerve sensitivity. Pain pathways can become more reactive, so normal inputs feel louder.
- Brain energy strain. Thinking, screens, and bright light can feel harder than usual, which can feed a migraine loop.
- Sleep disruption. Poor sleep lowers the headache threshold for many people.
- Neck strain. A whiplash-like jolt can irritate joints and muscles that refer pain into the head.
- Stress response. Adrenaline and tension can show up as clenched jaw, tight shoulders, and shallow sleep.
None of this means your brain is “broken.” It means your system is irritated and needs steady, boring care for a bit.
Signs Your Post-Injury Headache Fits A Migraine Pattern
Use this as a quick self-check. Migraine is more than head pain, so look for the bundle.
Common Migraine-Style Features
- Throbbing or pulsing pain
- Moderate to severe intensity that makes normal tasks hard
- Nausea or vomiting
- Light sensitivity or sound sensitivity
- Worse pain with movement
- Brain fog, slowed thinking, or trouble focusing
Features That Often Point To A Strong Neck Component
- Neck stiffness or soreness that started with the injury
- Pain that starts at the base of the skull and spreads forward
- Headache that spikes with turning your head or long phone use
Plenty of people have a mixed pattern. That’s normal after a jolt that hits both the brain and the neck.
Factors That Raise The Odds Of Migraine Symptoms After A Concussion
These factors often tilt the odds toward a migraine-style pattern:
- Personal migraine history or migraine in close family members
- Poor sleep in the first week
- High screen time, bright light, loud settings
- Neck pain or stiffness that started with the injury
What To Do In The First 48 Hours
The goal is to calm symptoms while you watch for change. A simple plan helps.
Step 1: Check For Danger Signs
If you have any red flags listed later in this article, seek urgent care. Trust your gut. A worsening headache after injury deserves prompt attention.
If you want a clean symptom list to compare against, the CDC HEADS UP concussion signs and symptoms page groups common concussion symptoms in one place.
Step 2: Take A Low-Stimulation Day
Keep lights softer if light hurts. Keep sound low if noise hurts. Use short screen bursts, then breaks. Gentle rest is fine. Try to keep a normal bedtime so nighttime sleep doesn’t fall apart.
Step 3: Hydrate And Eat Steadily
Dehydration and skipped meals can trigger migraine symptoms. Small, regular meals and steady fluids are often easier than big meals.
Step 4: Write A Symptom Note
Track the injury time, what happened, and what symptoms appear over the next two days. Write down headache intensity, nausea, light sensitivity, dizziness, and sleep. Bring it to your appointment.
Step 5: Protect Against Another Hit
Skip contact sports, risky climbs, and high-speed activities until a clinician clears you. A second injury during recovery can be serious.
Headache Patterns After Concussion: A Practical Comparison
These patterns can overlap, so this table is a sorting tool, not a diagnosis.
| Pattern | How It Often Feels | First Moves |
|---|---|---|
| Migraine-like post-traumatic headache | Throbbing pain, nausea, light or sound sensitivity, worse with movement | Lower stimulation, steady sleep and meals, medical evaluation for migraine-style plan |
| Tension-type pattern | Steady pressure, tight scalp or forehead, mild nausea at most | Neck stretches, posture breaks, heat or ice if it helps |
| Neck-driven (cervicogenic) pattern | Neck pain with headache that spreads forward, worse with neck motion | Neck assessment, gentle mobility work, reduce long phone posture |
| Exertion-triggered pattern | Headache flares with activity, settles with rest | Short walks under the symptom line, gradual activity build |
| Medication-overuse loop | Near-daily headache after frequent pain medicine use | Clinician plan to taper, consider prevention options |
| Sinus-like facial pressure | Face pressure with nasal symptoms, worse bending forward | Check allergy or cold triggers; avoid self-diagnosing infection |
| Concerning “new worst” headache | Sudden severe pain or fast worsening after injury | Urgent evaluation the same day |
| Mixed pattern | Two styles in the same week | Symptom log, treat neck and migraine triggers together |
How Long Migraine Symptoms Can Hang Around
Some people feel better in days. Others need a few weeks. If you’re still getting migraine-like attacks after a couple of weeks, it’s worth being rechecked. Persistent headaches can be part of a longer post-concussion symptom picture, and early care can prevent a cycle of repeated flares.
Ways To Reduce Migraine Triggers While You Heal
These habits sound plain. That’s the point. Migraine wiring tends to like steady routines.
Keep Sleep Boring
Pick a bedtime and wake time and stick close to it. Keep naps short. If your mind races at night, try a low-light wind-down: shower, quiet music, a paper book, slow breathing.
Use Screens With Guardrails
Lower brightness. Increase font size. Sit farther back. Use a timer for breaks. If scrolling triggers nausea, switch to audio or print for a few days.
Move In Small Doses
Start with an easy walk for five to ten minutes. Stop before symptoms spike. Add time in small steps across days. If your headache jumps, back off and try again later with a smaller dose.
Treat The Neck
If your neck is stiff, ask for an exam that includes neck range of motion and muscle tenderness. Guided therapy can help, and gentle heat can relax tight muscles.
When To Seek Medical Care Fast
After a concussion, get urgent evaluation if any of these show up. These signs can point to bleeding, swelling, or another serious issue.
| Danger Sign | What You Might Notice | Next Step |
|---|---|---|
| Worsening headache | Pain keeps climbing or feels different from earlier | Urgent care now |
| Repeated vomiting | More than once, or vomiting that starts later | Urgent care now |
| New weakness or numbness | Face droop, arm weakness, tingling that is new | Call emergency services |
| Speech or walking trouble | Slurred words, stumbling, new balance loss | Call emergency services |
| Seizure, collapse, or fainting | Shaking, loss of awareness, passing out | Call emergency services |
| Unequal pupils | One pupil looks larger than the other | Call emergency services |
| Confusion that gets worse | Agitation, unusual behavior, can’t stay awake | Urgent care now |
What A Clinician May Check
Expect questions about the injury, symptom timing, past headaches, sleep, and neck pain. Exams often include balance, eye tracking, memory checks, and a neck exam. If your symptoms are escalating, don’t wait it out.
The National Institute of Neurological Disorders and Stroke lists headache among common symptoms after traumatic brain injury and notes that symptoms can include dizziness, confusion, and fatigue. NINDS overview of traumatic brain injury is a plain-language summary.
Getting Back To Work, School, And Sports Without A Headache Spiral
Build back in steps. Start with short, calm tasks. Add time in small increments. Do the same with exercise: easy walking, then light cardio, then sport drills without contact, then contact only after clearance. If symptoms flare, drop back to the last level that felt steady for a day, then build again.
When Headaches Keep Returning
If migraine-like headaches keep returning, get re-evaluated. The pattern can be treated, and you don’t need to tough it out alone. A clinician can check for medication-overuse loops, sleep disruption, neck injury, and vision or balance problems that keep symptoms active.
Post-traumatic headache is often treated like the headache it resembles. That can mean migraine rescue medicines, nausea control, and prevention options when headaches are frequent. A tailored plan also reduces the chance that you end up taking pain relievers too often, which can feed a rebound cycle.
Summary Points
- A concussion can trigger migraine attacks or migraine-like post-traumatic headaches.
- Look for the migraine bundle: throbbing pain, nausea, light sensitivity, sound sensitivity, and worse pain with movement.
- Past migraine history, poor sleep, heavy screen time, and neck strain can raise the odds of migraine symptoms.
- Use a low-stimulation first day, steady meals and fluids, and a gradual return to screens and activity.
- Seek urgent care for danger signs like worsening headache, repeated vomiting, weakness, seizure, unequal pupils, or escalating confusion.
