Location and symptoms

A variation on exertional vascular headache, felt only when coughing, sneezing, bending or straining (including during a bowel movement)

Precipitating factors

In small number of people an obstruction blocking the flow through the normal fluid channels of the brain (the ventricles). In older patients, narrowing of the carotid arteries should be excluded

Treatment/prevention

Warrants a consultation with a general practitioner and/or neurologist to rule out structural abnormality. Benign form can be presented by use of indomethacin or a beta-blocking agent such as propranolol. May improve without treatment
