Description of Treatment Categories

There are several broad categories of treatments. Non-pharmacological includes devices that help with headaches, any therapy, for example massage or acupuncture, and behavioral changes. The other two categories are over-the-counter medications (buy at the drugstore) and prescription medications and injections.

Note: patients who have multiple types of headaches and may need specialized treatment for each sub-type.

This page provides detailed information about various headache treatments and the pathophysiology of post-concussive headaches. For a broader overview of post-concussive headaches, please visit our Headaches page.

Migraine

This shows the common areas of pain around the head of a patient with a migraine. It typically occurs all over the face. This image shows a head half highlighted red.

Symptoms can include:

  • Head-throbbing pain

  • Pain on one side of the head

  • Hypersensitivity to light and sound

  • Nausea

  • Dizziness

  • Aura

  • Pain worsens with activity

  • Vomiting (uncommon)

The biology of migraine headaches

Migraines are a common subtype of post-concussive headache. On the anatomical level, concussions cause a neuron’s axon to stretch or break, resulting in an imbalance of chemicals in the brain. This imbalance can signal neurons to depolarize (a cell’s energy charge becomes less negative/more positive) when they’re not supposed to. This leads to changes in the permeability of the blood-brain barrier, which can activate the trigeminal afferent nerve, which supplies the skin, mucous membranes, and sinuses of the face. If the depolarization reaches these neurons and the trigeminal nucleus caudalis (pain sensor areas of the outer region of the brain, see image below), it can create an inflammatory response, causing pain and headache. Neurons and pain sensitivity receptors also become more sensitive to pain and stimuli. This increased sensitivity explains why symptoms of migraines include nausea, dizziness, and hypersensitivity to light or sound. An individual’s genetic predisposition may also affect one’s pain levels following a migraine or trauma.

Treatments

Non-pharmacological (non-medication) and behavioral changes

  • Cefaly is a nerve stimulator for acute and preventative treatment of migraine headaches. Cefaly sends tiny electrical impulses to the trigeminal nerve, which is heavily involved in migraine pain. This reduces the frequency and intensity of migraine attacks. To learn more about Cefaly, visit our blog post about Cefaly or Cefaly’s website.

  • Heat packs are a therapeutic treatment most commonly applied to the head and neck. Therapeutic heat helps underlying muscles relax. To learn more about using a Heatpack, visit the National Headache Foundation.

  • Because concussions can affect the entire body, physical therapists can utilize a wide variety of physical therapy techniques for post-concussion headaches and decrease recovery time. Furthermore, the various sub-specialties of physical therapy can treat patients differently based on their symptoms. One systematic review found evidence that physical therapy can benefit concussion recovery by performing exercises that alleviate post-concussion symptoms, including stretching, strength, and range of motion exercises.

Over the counter (OTC) medications

  • Magnesium oxide (PO magnesium) is a supplement that treats migraines. PO magnesium is an over-the-counter supplement. Take PO magnesium at least 2 hours apart from other medications, and take it with food. Check with your healthcare provider that it will not interact with other medications you are taking. Evidence for the effectiveness of this treatment is demonstrated by this study and on page 89 of this document from the VA and DoD.

  • Melatonin is a supplement that supports concussion recovery by addressing headaches, neuroinflammation, and mood changes. Researchers believe that it helps with neuroinflammation because of its similar characteristics to a central nervous system therapeutic. Characteristics such as low toxicity, ability to cross the blood-brain barrier, and melatonin receptors that bind it to the central nervous system. Although more research is needed, studies show a promising trend. This study demonstrates evidence for its effectiveness. You can read about melatonin on our self-care page.

  • Riboflavin is a supplement that is used to treat migraines. Riboflavin is a strong antioxidant crucial for converting food to energy. Studies have shown a correlation between taking riboflavin and reducing the frequency or pain level headaches. See the following studies here, here, and here.

Prescription Pharmacological (medication)

  • Erenumub is an anti-migraine medication that works by preventing the start of the migraine. Erenurub targets the receptors for calcitonin gene-related peptide, a small protein involved in pain transmission in sensory nerves; its levels increase during a migraine. This study demonstrates evidence for its effectiveness. It is also addressed in this Concussion Alliance newsletter.

  • Botulinum Toxin, commonly called ‘Botox,’ is a prescription medication that treats migraines. The bacterium Clostridium botulinum produces the toxin that makes ‘Botox.’ Clostridium botulinum is commonly found in soil, plants, and soiled water. There are different brands of botulinum toxin. Specifically, dosages of Onabotulinum A helps treat chronic-type migraine headaches. Botulinum Toxin is injected into specific points around the head and neck to block the nerves so they produce less pain-inducing chemicals. Read more about it in this study.

  • Topiramate is a medication that treats various types of post-concussive headaches. In a study, topiramate blocks neuronal firing in the trigeminocervical complex, preventing a migraine from happening. It reduces the easily excitable neurotransmitters while enhancing neurotransmitters that act as a calming agent. It also prevents nerves from sending rapid and repetitive signals. In a study conducted on patients, 10% of them reported cognitive complaints. Based on the numbers, topiramate does not cause cognitive impairment and doesn't reflect in cognitive functions.

  • SSRIs (selective serotonin reuptake inhibitors) and SNRIs (serotonin-norepinephrine reuptake inhibitors) are medications that treat several conditions, including depression, PTSD symptoms, and migraines. They are important for managing mood change symptoms after a concussion..The link between serotonin and headaches is still unclear, but evidence suggests that low serotonin facilitates the activation of pain pathways that contribute to headaches. Read more about the evidence for their effectiveness here and here.

  • Triptans are medications that are used as a preventative measure, taken at the onset of a migraine. Triptans work by stimulating an increase of serotonin in your brain, which can help stop migraines. Read more about the evidence for their effectiveness on page 30 of this document.

  • Tricyclic antidepressants are medications that treat various types of post-concussive headaches. A type of tricyclic antidepressant, Amitriptyline, can also be used to treat insomnia. Tricyclic antidepressants are thought to preserve or increase neurotransmitters like serotonin, which helps treat migraines. Read more about the evidence for their effectiveness here and on page 89 of this source.

  • Sphenopalatine Ganglion Block is a powerful method of reducing post-concussion headaches by blocking and reducing pain signals from nerves in the sphenopalatine ganglion and its neural connections. Different treatments include injections, transnasal, transoral, and Infrazygomatic Approach. Read more about these treatments in the National Library of Medicine.

  • Propanal is known for treating repeated migraines. Usually used for heart problems, Proanal is a type of beta-blocker (a medication that lowers blood pressure). It stabilizes serotonin levels, preventing your blood vessels from widening. Read more about Propranolol on this page.

Cervicogenic headache

This image shows common areas of pain for individuals with cervicogenic headaches. This includes around the eye, forehead, temple, and back of the neck.

Symptoms can include:

  • Neck pain

  • Pain around the eye

  • Dizziness

  • Blurred vision

  • Balance problems

  • Poor concentration or memory

The biology of Cervicogenic headaches

Diagram by Micah Jay Strike

Neck trauma, whiplash, strain, or chronic spasms of the scalp, neck, or shoulder muscles can cause injury to the C1-C3 nerves in the cervical spine (neck). The pain could be referred pain, ( the pain originates in a different part of the body than it is felt). The cervical spine's superior three nerves (C1, C2, C3) are thought to be responsible for the pain experienced in cervicogenic headaches. Inflammation and neurotransmission through these injured nerves are thought to produce or exacerbate the pain of the headache. Any body part that the C1–C3 spinal nerves branch out to could be the source of pain for a cervicogenic headache. A primary example would be the shoulder area and the occipital area in the back of the skull, which have nerves connected to the C1-C3 spinal nerves.

  • Cefaly is a nerve stimulator for acute and preventative treatment of migraine headaches. Cefaly sends tiny electrical impulses to the trigeminal nerve, which is heavily involved in migraine pain. This reduces the frequency and intensity of migraine attacks. To learn more about Cefaly, visit our blog post about Cefaly or Cefaly’s website.

  • Manual therapy is a specialty of physical therapy that can help treat post-concussion headaches. It primarily involves the kneading and manipulation of muscles, joint mobilization, and joint manipulation. It often involves working on the biomechanical, tissue-based examination to determine the cause of post-concussion headaches.

Over the counter (OTC) medications

  • Cannabidiol (CBD) may treat various post-concussion symptoms, including pain, mood changes, and sleep disturbance. The way CBD affects the body can be found here. Read about research being done on this treatment here.

Prescription Pharmacological

  • Tricyclic antidepressants are medications that treat various types of post-concussive headaches. A type of tricyclic antidepressant, Amitriptyline, can also be used to treat insomnia. Tricyclic antidepressants are thought to preserve or increase neurotransmitters like serotonin, which helps treat migraines. Read more about the evidence for their effectiveness here and on page 89 of this source.

Tension “Stress” headache

This image shows common areas of pain associated with tension headaches. These include the forehead, temple, jaw, and back of the neck.

Symptoms can include:

  • Usually mild to moderate pain

  • Band-like pressure around the head or forehead

  • Joints in the jaw may be irritated, cramped or aching (could also be TMJ headache)

  • Usually NO nausea

  • Usually NO hypersensitivity to stimuli

The biology of Tension “Stress” headaches

Tension headaches are the second most common type of post-concussive headache, behind migraines. Stress and mental tension may worsen a post-concussive tension headache, although the specific processes that contribute to this headache are still unclear. Studies have shown that emotional factors like stress, anxiety, and depression may also lead to the development of tension headaches. 

It is currently believed that input from trigger points in inflamed or tender pericranial muscles causes pain pathways to be activated, causing headaches. Pericranial muscles are the outer bands of muscle surrounding the skull and neck, with trigger points often but not always starting from the third occipital nerve. This can result from changes in neurotransmitter concentrations, particularly serotonin by causing blood vessels to become dilated. An inadequate blood supply or disturbances in metabolism, capillaries, and mitochondria function in the tender areas may explain the pain.

In association with a concussion, injury to the neck or surrounding muscles of the face can produce conditions that are conducive to tension headaches.

Treatments

Non-pharmacological (non-medication) plus behavioral changes

  • Dry needling is a physical treatment similar to acupuncture that treats various types of post-concussive headaches. According to the VA, dry needling is used for post-concussive headaches with “tension features.” It targets trigger points that cause the tension or pain of a headache. Read more from the VA here.

  • Acetaminophen (Tylenol is a common brand) helps manage physical pain. During the first 24 hours, avoid ibuprofen, aspirin, or any other medications that could put you at risk of bleeding. Read more about acetaminophen on the Mayo Clinic page and the University of Michigan Health page.

  • Topiramate is a medication that treats various types of post-concussive headaches. In a study, topiramate blocks neuronal firing in the trigeminocervical complex, preventing a migraine from happening.

Prescription Pharmacological

Neuritic and neuralgic headache

This shows common areas of pain associated with neuritic and neuralgic headaches. The pain comes from the posterior scalp and upper neck.

Symptoms can include:

  • Sharp, intense stabbing pain around the craniocervical junction (where the back of the head connects with the neck)

  • Tenderness or numbness upon touching the occipital region (back of the head)

  • Pain behind the eyes

  • Neck pain

The biology of neuritic and neuralgic headaches

The occipital nerves sit at the back of your head. Injury or disruption to these nerves from a concussion can cause a painful condition called occipital neuralgia, which is one common type of neuralgic headache.

Furthermore, the sharp, shooting sensation in the occipital nerve area associated with neuralgic headaches can stem from a pinched or injured nerve in the cervical spine. Injury or inflammation to blood vessels in the brain or neck can also injure the nerves and cause shooting pain associated with neuralgic headaches.

Treatments

  • Tricyclic antidepressants are medications that treat various types of post-concussive headaches. A type of tricyclic antidepressant, Amitriptyline, can also be used to treat insomnia.

Prescription Pharmacological

TMJ Headache

This image shows common areas of pain associated with TMJ headaches. This includes the jaw and side of the head.

Symptoms can include:

  • Jaw pain

  • Restricted jaw movement

  • Clicking when jaw opens

  • Tight facial or jaw muscles

  • Earache

The biology of TMJ headaches

Diagram by Micah Jay Strike

A blow to the jaw or a whiplash injury during a concussive event can result in a TMJ headache. Inflammation in the temporomandibular joint (TMJ) can spread to nearby muscles and joints in the jaw, creating a painful sensation and muscle tightness that translates into a headache. However, the correlation between pain and injured tissues is often not obvious; not all patients have a clearly identifiable physical condition.

MRI studies in TMD (temporomandibular disorders) have provided evidence for changes within the pain stimulus pathway involving different parts of the brain like the trigeminal nerve root, subnucleus caudalis (SpVc), and thalamus. These new findings could be the cause of pain in TMJ headaches.

Treatments

Non-pharmacological (non-medication) plus behavioral changes

  • Therapeutic cold blocks or slows down nerve conduction. At first, the cold will cause muscles to tighten, but after a while, it relaxes the muscles because of the restricted nerve conduction.

  • Because concussions can affect the entire body, physical therapists can utilize a wide variety of physical therapy techniques for post-concussion headaches and decrease recovery time. Furthermore, the various sub-specialties of physical therapy can treat patients differently based on their symptoms.
