Understanding Post Concussive Headache: Overview and Prevalence
Quick take: A headache after a head injury is common, but if it gets worse or comes with new warning signs, you need to act fast.
If you have any of these emergency signs, call emergency services now:
- A sudden, very bad headache
- Worsening confusion or trouble staying awake
- Problems with balance or walking
- New seizures
A concussion is a mild head injury that can make you dizzy, confused, or off-balance. After a head injury, you might get a headache that sticks around for weeks, months, or even years. In fact, about 70%-84% of people with mild head injuries say they get a headache. This headache is one part of post concussion syndrome, which can also include mood changes, sleep troubles, and thinking problems.
You may notice that your headache won’t go away, and you might feel dizzy or have trouble remembering things or focusing. Mood swings and feeling very tired are also common. People playing
Causes of Post Concussive Headache: Pathways and Risk Factors
After a head injury, your brain may not work like it did before. One main problem is that your body’s automatic system (which controls your heart rate and breathing) loses its balance. Also, the connection between blood flow and brain activity can break down. This disruption can cause different headache patterns.
Some factors can raise your risk of a headache after a concussion. Neck issues can start a type of headache that actually comes from the neck. Problems at the base of your neck may upset your automatic system, leading to headache pain. Migrainous post-traumatic headaches often bring one-sided, stabbing pain along with light sensitivity, sound sensitivity, and nausea. If you have a history of migraines, you may face longer-lasting symptoms and a slower recovery.
It is important to know what can cause headaches after a concussion. Watch for these three key clues:
- A history of migraines
- Signs of a severe head injury, such as bruising around the eyes or on the side of the head
- Problems with the cervical spine or neck
Recognizing these clues can help your doctor choose the best care to manage your post-concussion headache.
Symptoms and Types of Post Concussive Headache
Quick take: Post concussion headaches can feel very different from person to person. They may be dull or sharp, and they can come with extra signs like nausea or sensitivity to light and sound.
Triage:
• Call emergency services now if you have worsening confusion, repeated vomiting, seizures, or feel very unsteady.
• Seek same-day care if the headache suddenly gets much worse or you notice new changes in your vision or behavior.
• Rest and note your symptoms if they are mild and steady.
After a head injury, you might get a headache that feels like a tight band across your head or a sharp pain on one side that can resemble a migraine. Many people find that their headache comes with eye strain, nausea, or high sensitivity to light and sound. Sometimes, movement or thinking harder can make your head feel heavy or create a crown-like pressure.
There are three common types of post concussion headaches:
• Migrainous: You experience a strong, throbbing pain on one side near the top of your head.
• Cervicogenic: The pain starts at the back of your head and neck (neck stiffness) and moves forward.
• ANS dysregulation: Changes in your body’s automatic system create odd feelings and muscle tightness, sometimes with a crown-like sensation that gets worse with activity.
Knowing which headache you have can help guide your treatment. For instance, if you notice that moving your neck makes the pain worse, it may be a cervicogenic headache.
| Headache Type | Key Features | Typical Duration |
|---|---|---|
| Cervicogenic | Pain starts at the back, neck stiffness | Hours to days |
| ANS Dysregulation | Crown sensation, worsens with activity | Variable |
| Migrainous | Side throbbing pain, light sensitivity, nausea | Hours up to 72 hours |
Keep a simple record of your symptoms. Write down what makes the headache start or change, any new dizziness or eye strain you feel, and report these details to your clinician. This clear record helps your doctor decide the best steps to help you feel better.
Diagnosing Post Concussive Headache: Criteria and Evaluation
Quick take: A headache that starts within 7 days after a bump on the head might be linked to your injury.
Triage Box:
If you have any of these signs, call emergency services now:
- Bruising around the eyes (raccoon eyes)
- Bruising behind the ears (battle signs)
- Ongoing vomiting
- Seizures
If these occur, you may need a CT scan or MRI to check for a skull fracture or brain bleeding.
Doctors decide if your headache is from a head injury by using trusted guidelines from the International Headache Society. They ask when your headache began, how the pain feels, what seems to trigger it, and what makes it better. This detailed history helps them choose the best tests, including imaging, when needed.
A careful physical exam is also done. Your doctor checks how well you can turn your head 45 degrees on each side and performs simple tests for your brain, memory, and concentration. Recording your symptoms, including their start time and intensity, is key. These details also help identify the ICD-10 code G44.31 for persistent post concussive headache and tie into standard concussion rules like the DSM-5 criteria and Canadian guidelines.
Treatment Strategies for Post Concussive Headache
Quick take: Most post-concussion headaches can be managed with simple medications, self-care, and gentle therapies.
Triage Box:
• If you experience new or worsening symptoms like confusion, trouble walking, or weakness, call emergency services.
• If your pain does not improve or gets worse after a few days, seek same-day medical advice.
• Track your symptoms and note any changes to share with your doctor.
Managing head pain after a concussion often means using a mix of safe medications, smart self-care, and gentle therapies. Early treatment focuses on lowering pain and inflammation while helping your body heal naturally. This balanced plan can ease your discomfort now and support your long-term recovery.
Medication Management
In the first 48 hours after your injury, acetaminophen (Tylenol) is a safe choice to reduce pain. After this period, and if your doctor feels it is safe, non-steroidal anti-inflammatory drugs like ibuprofen or Aleve can further relieve pain. If your headache continues or gets worse, your doctor may suggest a prescription medicine. Always check with your clinician before starting a new drug.
Non-Pharmacological Therapies
Taking care of yourself is key. Drink plenty of water, get enough sleep, and eat a balanced diet to support brain healing. Some people find that supplements like omega-3 fatty acids, magnesium glycinate, and CoQ10 help lower inflammation. You can also try gentle exercise, as long as you stay below your symptom threshold. These steps work together to ease pain naturally and build a strong base for recovery.
Advanced Interventions
When basic methods do not provide enough relief, there are additional treatments to try. Physical therapy, including neck exercises and vestibular rehabilitation (balance training), may help reduce pain and improve movement. Acupuncture can be an option for headache patterns similar to migraines, while postural work may ease neck-related pain. In some cases, doctors might consider a nerve block to help with severe or stubborn headache symptoms.
Taking a step-by-step approach and adjusting your plan over time can make your headache easier to manage. Stay in touch with your doctor as you track your symptoms so that your treatment plan can be safely tailored to your needs.
Recovery Timeline and Self-Congcussive Headache: Feel Better Today
Quick take: Recovery from a concussion takes time, so go slowly and track your symptoms.
Call emergency services now if you have any of these signs:
- A sudden, severe headache that gets worse quickly.
- New confusion, weakness, or a sudden change in behavior.
- Loss of consciousness or repeated vomiting.
Urgent: Seek same-day care if your symptoms worsen or you notice new issues.
Watch and self-manage: Follow your provider’s guidance, rest, and gradually return to normal activities.
Recovery from a concussion happens in clear stages. In the first 7 days (acute phase), you may feel off and need plenty of rest because your symptoms can be unpredictable. From about day 7 to day 30 (subacute phase), most people start feeling better gradually. However, 10–15% of people may experience headaches or other symptoms for more than 30 days (chronic phase). Knowing these phases can help you ease back into your daily routine safely.
It is vital to follow your doctor’s return-to-play or return-to-learn advice. Begin with light tasks that do not make your headache worse and slowly add more activity as you feel ready. This careful, step-by-step approach helps prevent setbacks and supports your brain’s healing process.
Keeping a headache log is a simple way to monitor your progress. Each time you have a headache, note the date, time, and how strong the pain feels. Write down what might trigger the headache or what helps ease it. This record can be very helpful when you discuss your recovery with your clinician.
Adjusting your daily routine to fit your current energy and symptoms is also key. Take regular breaks, eat balanced meals, and engage in gentle exercise that does not push you past your symptom limits. With careful monitoring and gradual changes, you can manage lingering head pain and work towards a safer return to your everyday activities.
Recognizing Red Flags in Post Concussive Headache
If your headache isn’t getting better like you expect, you need to follow up with your doctor soon.
Set up appointments about 1 week and 1 month after your injury so your doctor can review your progress and make changes to your care plan. If your headache lasts more than 2 weeks despite initial treatment, talk to a neurologist or concussion specialist to check for hidden issues.
Staying on top of your symptoms helps you and your doctor act fast to keep you safe and avoid long-term pain.
