What is it?
A headache is a persistent pain, usually a dull ache, in the head. Migraines involve more localised, throbbing pain often accompanied by nausea or vomiting and sometimes visual and neurological problems.
Signs and symptoms
Tension headaches are characterised by muscle tension and aching pain that often radiates from the forehead, the back of the neck and the jaw.
'Common' migraines' (also called 'migraine without aura') involve throbbing pain, usually on one side of the head, and are often accompanied by light sensitivity, nausea or vomiting.
'Migraine with aura' or 'classic' migraines are preceded by symptoms that may include visual disturbance, extreme sensitivity to light, sounds and smells, speech problems and muscle weakness, nausea and vomiting. Following these symptoms intense pain begins and can
continue for hours, or even days.
