Migraines and Cluster Headaches

Migraine

Symptoms traditionally associated with migraine may begin before, during or less commonly, after the pain of the headache.

The most characteristic symptom is a change in vision. This manifests as an area of disturbed sight, in the form of flashing lights or bars beginning in the centre of vision. It grows larger and moves out towards one side. A patch of dimmed or decreased vision follows where the bright light had been. In less than an hour, the vision returns to normal.

There are very few conditions, which produce this pattern of visual change, and it is almost exclusively associated with migraine.  It is more common to have less dramatic changes in sight. People often describe their vision as blurry. Eye pain, tenderness, and light sensitivity are very frequent.

Dizziness and stomach upset, including vomiting, can occur. Tingling sensations, mild weakness on one side of the body or speech problems may be part of a headache episode. Some headache patients faint during an attack. Such symptoms are more worrisome and must be evaluated by a doctor.

Cluster Headache

A Special And Uncommon Primary Headache Type

The term "cluster headache" refers to a rare, but distinctive form of pain, which is centered on one eye. There are other unique features and the diagnosis has to be made by an experienced doctor who is familiar with the condition.
