Sex headaches

Any type of sexual activity that leads to orgasm can trigger sex headaches.

Sex headaches that come on suddenly are more likely to be associated with:

A widening or bubble in the wall of an artery inside your head (intracranial aneurysm)
An abnormal connection between arteries and veins in the brain (arteriovenous malformation) that bleeds into the spinal fluid-filled space in and around the brain
Bleeding into the wall of an artery leading to the brain (dissection)
Coronary artery disease
Use of some medications, such as birth control pills
Inflammation from certain infections

Sex headaches associated with loss of consciousness, vomiting, stiff neck, other neurological symptoms and severe pain lasting more than 24 hours are more likely to be due to an underlying cause.

Sex headaches can affect anyone. But risk factors for these headaches include:
Being male. Men are more prone to having sex headaches.
