Primary Exertional Headache (Exercise Headache)
A headache that comes on with hard physical effort, such as running or lifting, or with straining. Because a few serious problems can look the same, a first episode should always be checked by a doctor.
What is primary exertional headache?
Exertional headache is a headache brought on by physical effort. It is also called exercise headache. The word “primary” means the headache is the condition itself. It is not a sign of another problem, such as bleeding or a blood vessel problem in the brain.
That difference is the most important thing to know. A sudden, severe headache during exertion can sometimes come from a serious cause. A doctor can only call it primary exertional headache after checking for those causes and finding none.
Common symptoms
- A headache that often begins abruptly during or right after effort
- Pain felt across the head rather than in one spot
- Pain that is usually short-lived but can last as long as 48 hours
What can trigger it
Triggers fall into two groups:
- Strenuous activity, such as running, jumping or sexual activity, including orgasm
- Straining, such as coughing, sneezing or bearing down during a bowel movement
Exercise can also set off attacks in people who have migraine. Migraine pain often gets worse with routine physical activity, and a hard workout can push some people past their migraine threshold. That is different from primary exertional headache, and a doctor can help tell them apart.
How it is diagnosed
The National Headache Foundation advises a neurological evaluation and brain imaging for exertional headache. Headaches set off by coughing, sneezing, bending over, exercise or sexual activity are on its list of headaches that call for medical attention.
The goal is to rule out dangerous causes. Bleeding from a weak spot in a blood vessel (an aneurysm) or a tear in an artery wall (a dissection) can begin after exertion such as lifting weights. A severe headache during sex can also signal one of these problems. Tests may include a CT scan, MRI or other images of the blood vessels, and sometimes a lumbar puncture (spinal tap).
When headaches with the same activity keep coming back over a long time, they are much less likely to be dangerous. Your doctor will still want to hear about any change in their pattern.
Treatment options
Once serious causes are ruled out, treatment is tailored to you. Options the sources describe include:
- Indomethacin, an anti-inflammatory medicine, which is one of the most common treatments
- Propranolol, a blood pressure medicine also used to prevent some headaches
- Medicine taken before activity. In some people, a triptan or an ergotamine (migraine-specific medicines) taken ahead of time may help.
- A daily preventive, often a blood pressure medicine, for people whose sex-related headaches are frequent
For people with migraine who want to stay active, physical therapists who work with headache patients suggest starting at a realistic level, building up slowly, and easing back on hard days rather than doing too much, too soon, too often or too hard. Regular exercise over time may lower overall migraine risk for some people.
How Dr. Park can help
Dr. Hannah Park is a dual board-certified, fellowship-trained headache medicine neurologist with over 10 years of specialized experience, and she has lived with migraine herself. She treats primary exertional headache.
Every patient starts with a 90-minute new patient consultation with Dr. Park ($520): a full history review, a neurological exam, a diagnosis and a personalized treatment plan. If your headaches have not yet been checked for other causes, this visit is a place to start that conversation. See services and fees.
Appointments are Monday to Friday, 9 a.m. to 6 p.m., usually within days. The practice is direct pay with no referral needed.
When to get emergency care
Call 911 or go to the nearest emergency room for a first-ever sudden, severe headache that reaches full strength within about a minute, especially during exercise, lifting, straining or sex, or one that does not go away when you stop. Also get emergency care for a headache with fever, weakness, confusion, loss of vision or feeling, or changes in speech or thinking.
