Chronic Daily Headaches
What are chronic daily headaches?
Chronic daily headache describes a group of headache disorders in which headache pain occurs at least 15 days per month during a 3-month period. True (primary) chronic daily headaches are not caused by another condition.
These headaches include:
- Chronic migraine
- Chronic tension-type headache
- Medication overuse headache (rebound headache)
- Hemicrania continua
- New daily persistent headache

Chronic Daily Headaches Symptoms
By definition, chronic daily headaches occur at least 15 days per month during a 3-month period.

Chronic Daily Headaches Treatments
Treatments that try to stop or reduce headache symptoms before or shortly after they start have a greater chance of reducing the frequency of chronic headaches than treatments administered after headache symptoms have begun.
Abortive medications—the name for drugs used to treat headache symptoms that have already begun—can cause medication overuse “rebound” headaches if taken too frequently. This can start a cycle in which the medicine, while providing brief relief, ends up causing more headaches over time.

Some medications originally intended for other uses can be effective at preventing chronic daily headaches, such as:
- Anti-depressants
- Beta blockers
- Anti-seizure medications
Botox can be used for the prevention of chronic migraines, but insurance companies usually require people to try preventative medications before they will cover Botox. Botox injections are performed in 31 sites on the head and neck every 12 weeks and can be very effective in reducing the frequency and severity of migraines.

Causes of Chronic Daily Headache
Doctors are not exactly sure what causes chronic daily headaches. True, or primary, chronic daily headaches do not have a cause that can be identified. That does not, however, mean that they cannot be treated.
