A headache that starts after a head injury is not just a headache. For millions of people recovering from a concussion or traumatic brain injury (TBI), headache becomes the most persistent — and most disabling — symptom of their recovery. If you are searching for answers about post-traumatic headache treatment, you are in the right place. This guide covers what post-traumatic headache actually is, why it can linger for months, and the seven treatment approaches that clinical evidence supports most strongly.
What Is Post-Traumatic Headache?
Post-traumatic headache (PTH) is classified as a secondary headache disorder — meaning it develops as a direct consequence of another condition, in this case head trauma or TBI.
According to the International Classification of Headache Disorders, Third Edition (ICHD-3), PTH is defined as a headache that begins within seven days of the head injury, within seven days of regaining consciousness, or within seven days of recovering the ability to perceive and report pain.
This precise definition matters because it helps clinicians determine whether a headache is truly injury-related — and it guides treatment decisions accordingly.
Acute vs. Persistent Post-Traumatic Headache
PTH is divided into two categories based on how long it lasts. Acute post-traumatic headache resolves within three months of onset. Persistent post-traumatic headache continues beyond three months and may become a chronic, daily condition.
This distinction is not merely academic. The two categories often require different treatment strategies, different levels of specialist involvement, and a very different conversation about prognosis.
How Common Is Headache After Concussion?
Headache is the single most common physical complaint following traumatic brain injury. Depending on the study and the definition used, prevalence estimates range from 30% to as high as 90% of TBI patients — with the highest rates seen after mild TBI and concussion.
Between 18% and 22% of patients still report headaches one year after their injury. That means for a significant portion of people, TBI headache is not a short-term inconvenience — it is a long-term medical condition.
Several factors increase the risk that a headache after concussion will persist. A personal history of migraines or primary headaches is the strongest predictor. Female sex, younger age, greater initial injury severity, and co-occurring conditions such as anxiety, depression, or post-traumatic stress disorder (PTSD) also increase the likelihood of chronic PTH.
Migraine-Like vs. Tension-Type: Identifying Your PTH Pattern
Not all post-traumatic headaches feel the same, and identifying the pattern matters — because the phenotype, or clinical presentation, directly guides which treatment is most likely to work.
Migraine-Like Post-Traumatic Headache
The migraine phenotype is the most common presentation, affecting roughly half of all PTH patients. It typically presents as a throbbing or pulsating pain, often on one side of the head, accompanied by nausea, light sensitivity (photophobia), and sound sensitivity (phonophobia). Some patients also experience aura.
This presentation shares so much overlap with primary migraine that clinicians often use migraine-targeted treatments as the first approach.
Tension-Type Post-Traumatic Headache
The tension-type phenotype presents as a dull, bilateral pressure or tightening sensation around the head — like a tight band or clamp. Pain is usually mild to moderate and does not typically involve nausea or light sensitivity.
Tension-type PTH is particularly common in patients with cervical muscle involvement or whiplash injury, and it often responds well to physical therapy and non-pharmacological approaches.
Other Subtypes
Some patients present with cervicogenic headache, where the pain originates from the neck and radiates forward. Others may develop new daily persistent headache (NDPH) or occipital neuralgia, particularly after more significant head trauma.
Because no two patients present identically, phenotyping — identifying which category your headache most resembles — is a critical first step in designing an effective treatment plan.
How Long Does Post-Traumatic Headache Last?
This is one of the most searched questions about PTH, and the honest answer is: it depends on the individual, the severity of the injury, and whether the right treatments are pursued early.
For the majority of people, post-traumatic headache after a mild TBI or concussion improves significantly within the first few weeks to three months. Acute PTH often resolves as the brain recovers and inflammation subsides.
However, a meaningful subset of patients transitions into persistent post-traumatic headache. Research suggests that between 18% and 22% of TBI patients still report headaches one year after injury. These individuals are at risk of developing chronic daily headache if the condition goes untreated.
If your concussion headache is not going away — especially if it has been more than eight to twelve weeks without improvement — that is a signal to escalate care beyond over-the-counter management. Persistent PTH does not typically resolve on its own without targeted intervention.
7 Post-Traumatic Headache Treatment Options
Treatment for headache after brain injury works best when it matches the headache phenotype and accounts for any co-occurring conditions. Here is a breakdown of the seven most clinically supported approaches.
1. NSAIDs and Analgesics (Acute/Abortive)
For the first few weeks after TBI, over-the-counter NSAIDs such as ibuprofen or naproxen are appropriate first-line agents for managing acute headache pain. Acetaminophen is also used, particularly in patients who cannot tolerate NSAIDs.
These medications reduce inflammation and interrupt pain signaling, providing relief when used appropriately. The critical caution here is frequency of use. Relying on abortive analgesics more than two to three days per week puts patients at risk of medication overuse headache — a rebound phenomenon discussed in detail below.
2. Triptans for Migraine-Phenotype PTH
When post-traumatic headache presents with migraine-like features — throbbing pain, nausea, photophobia — triptans are a clinically logical option. Sumatriptan and other serotonin receptor agonists work by constricting dilated cranial blood vessels, blocking pain transmission along the trigeminal nerve, and reducing inflammatory neuropeptide release.
Triptans are not preventive — they are taken at the onset of an attack to abort it. For patients whose TBI headache fits a clear migraine phenotype, they can be remarkably effective. For a detailed comparison of triptan options and how they differ, see our guide to the best migraine medications.
3. Tricyclic Antidepressants — Amitriptyline as a Preventive
Low-dose amitriptyline, typically 10–75 mg at bedtime, is one of the most commonly used preventive medications for both tension-type and migraine-phenotype PTH. It works by modulating pain-signaling pathways in the central nervous system, independent of its antidepressant effects at higher doses.
A preventive medication is taken daily regardless of whether a headache is present. The goal is to reduce the frequency, severity, and duration of future attacks — not to stop a headache that is already in progress. Patients should expect four to eight weeks before evaluating whether amitriptyline is working.
4. CGRP Monoclonal Antibodies — A Newer Preventive Approach
Calcitonin gene-related peptide (CGRP) is a neuropeptide that plays a central role in migraine pathophysiology — and emerging research suggests it is also involved in the initiation and persistence of post-traumatic headache. CGRP is released during trigeminovascular activation, contributing to the inflammatory cascade that drives headache pain.
CGRP monoclonal antibodies — including erenumab (Aimovig), fremanezumab (Ajovy), and galcanezumab (Emgality) — were developed to block this pathway in chronic migraine. These medications are now being explored in patients with persistent PTH who have failed other preventive agents.
For patients with persistent post-traumatic headache that mirrors chronic migraine and has not responded to first-line preventives, CGRP-targeted therapy represents one of the most promising newer options available. A detailed review of CGRP’s role in PTH can be found in published research at PMC.
5. Physical Therapy for Cervicogenic and Musculoskeletal Drivers
Many cases of TBI headache — particularly tension-type and cervicogenic presentations — have a significant musculoskeletal component. Cervical muscle spasm, joint hypomobility, and poor postural mechanics after a head or neck injury can perpetuate headache pain long after the initial injury.
Physical therapy addresses these drivers directly. Treatment may include cervical mobilization and manipulation, soft tissue work, postural correction, and a progressive return-to-activity program. For patients whose headache originates in the neck or worsens with specific postures or movements, physical therapy is not just supportive — it is a primary treatment.
6. Biofeedback and Cognitive Behavioral Therapy (CBT)
Non-pharmacological approaches have strong evidence in persistent headache disorders — and they are particularly valuable in PTH patients who also struggle with anxiety, depression, or PTSD.
Biofeedback teaches patients to consciously regulate physiological responses such as muscle tension, heart rate, and skin temperature, helping interrupt the physical patterns that trigger or worsen headaches. CBT helps patients identify and modify thought patterns and behaviors that amplify pain perception and disability.
The value of these approaches goes beyond headache. Because PTH so often co-occurs with post-concussion syndrome, mood changes, and sleep disruption, addressing the psychological and behavioral dimensions of recovery produces meaningful improvements across the entire symptom cluster.
7. Interventional Options — Nerve Blocks and Sphenopalatine Ganglion Block
For patients with refractory post-traumatic headache who have not responded to medication and physical therapy, interventional procedures represent the next step.
Occipital nerve blocks — injections of local anesthetic with or without corticosteroid into the occipital nerve — can provide significant relief in patients with posterior headache or occipital neuralgia following TBI. Cervical trigger point injections target areas of focal muscle hyperalgesia in the neck and upper back.
The sphenopalatine ganglion (SPG) block is a newer interventional option that has shown promising results in chronic post-traumatic headache, administered via a small catheter through the nose with essentially no recovery time. For patients who have been suffering for more than a year with headaches that have not responded to standard treatment, this type of specialist-level care can produce dramatic results.
The Medication Overuse Headache Risk in PTH
One of the most important — and most overlooked — complications of post-traumatic headache management is medication overuse headache (MOH), sometimes called rebound headache.
MOH develops when abortive pain medications are used too frequently. For most classes of headache medications, this threshold is more than two to three days per week. When crossed regularly, the medications that were meant to relieve headache begin to perpetuate it — creating a cycle that can be extremely difficult to break without medical supervision.
Patients who are managing TBI headache with daily or near-daily OTC analgesics are at high risk. If you are taking pain medication for headache on more than three days per week and your headaches are getting worse rather than better, medication overuse may be contributing to the problem. A supervised taper under a physician’s guidance is typically required to break the cycle.
When Should Persistent Post-Traumatic Headache See a Specialist?
Most people with post-traumatic headache manage adequately with their primary care physician in the early weeks of recovery. But there are clear signals that it is time to seek specialist evaluation.
You should seek urgent or emergency care if your headache is sudden and severe, unlike any you have had before, or is accompanied by confusion, weakness, vision changes, or neck stiffness. These can signal serious complications that require immediate imaging.
You should seek specialist evaluation — with a neurologist or pain medicine specialist — if your headache has persisted beyond three months without significant improvement, if it is interfering with work, sleep, or daily activities, if you have tried two or more medications without adequate relief, or if you suspect medication overuse has become a factor.
At that point, you are no longer dealing with routine post-injury recovery. Persistent post-traumatic headache is a distinct diagnosis that warrants a dedicated, multidisciplinary treatment plan — including the full spectrum of pharmacological, behavioral, and potentially interventional options outlined in this article.

Taking the Next Step
Post-traumatic headache is real, it is common, and it is treatable. The key is matching the right treatment to the right headache type — and not waiting too long to escalate care when first-line approaches are not working.
Whether your TBI headache resembles migraine, tension-type, or something more complex, there is a structured path toward better function and less pain. Do not accept persistent headache as an inevitable consequence of your injury. Effective post-traumatic headache treatment is available, and the earlier it is pursued, the better the outcome.
