Types
Primary exercise headache
A throbbing headache, sometimes with sickness or sensitivity to light, that comes on during or soon after exercise. It's more likely in hot or humid weather or at altitude. It's harmless, but other causes must be ruled out first, sometimes with a scan.
Cardiac cephalalgia
Rarely, a headache on exertion is caused by heart disease. It eases with rest and may come with chest, arm or neck discomfort, breathlessness or sweating. It needs heart tests, and triptans must not be used.
Treatment
For primary exercise headache, a longer warm-up and building up exercise gradually often help. Some people take indomethacin before exercise, with stomach protection, on a doctor's advice.
When to get urgent help
Call 999 if you have
- a sudden, extremely bad headache during exercise or sex
- headache with chest pain, breathlessness or sweating
- weakness, numbness or slurred speech
Call NHS 111 if
- you have a headache brought on by exercise for the first time
See your GP if
- headaches keep coming on with exercise
- you have a headache brought on by coughing or straining
Work and your workspace
Migraine can count as a disability under the Equality Act 2010 (the Disability Discrimination Act in Northern Ireland) if it has a substantial, long-term effect on your everyday life. Conditions that come and go still count, and the law looks at how you would be without treatment. If it applies, your employer must make reasonable adjustments.
Adjustments that often help
- Avoiding heavy physical tasks until diagnosed
- Flexible hours
- Time off for appointments
A migraine-friendly workspace
- A chair with good lumbar and neck support
- A desk big enough to put your screen at arm's length
- Screen raised so the top is at eye level
- A flicker-free monitor with an anti-glare or blue-light filter
- Lighting without flicker or glare, and blinds to control daylight
Access to Work can pay towards equipment and support. Acas and Citizens Advice give free advice on your rights.
How The Beyond Pain Foundation can help
If NHS waits are too long, or the help you need is not available to you on the NHS, we may be able to fund:
- A private specialist appointment to rule out serious causes sooner
- Travel to specialist appointments
Every award depends on your situation and the funds we have that month. A letter from your doctor, a headache diary and a written quote all help your application.
