Description:

Headaches are a common health complaint suffered by almost everyone. A careful diagnosis of the cause is important.

Symptoms:

Two types: those caused by muscle contraction and vascular irregularities (the alternation of constriction and expansion of the arteries). Migraine symptoms include lightheadedness, a throbbing pain on one side of the head, nausea, vomiting, dizziness, blurred vision, hot and cold flashes and hypersensitivity to light, sound and movement. Migraine pain is most often severe and localized on one side of the head, usually involving the temple and the eye. Sufferers may experience warning symptoms a few minutes before the migraine, including blurred vision, muddled thinking, exhaustion, nebula of lights and numbness or tingling on one side of the body. Cluster headache symptoms include excruciating pain concentrated around the eye, tears, facial flushing and nasal congestion. Sharp intense pain afflicts the victim for a few hours and subsides only to return in a few hours. These attacks can last anywhere from a few weeks to several months.
