Headache

A headache is any pain arising from the head or upper neck of the body. The pain originates from the tissues and structures that surround the brain. This pain may be a dull ache, sharp, throbbing, constant, mild, or intense. A headache can last less than an hour or for several days.

While typically benign, occasionally a headache can be an indicator of a more serious condition. Your headache symptoms can help your doctor determine the cause and the appropriate treatment. Headaches are generally classified by cause. Primary headaches include migraines, tension headaches, and cluster headaches. Secondary headaches are usually symptoms of an injury or an underlying illness.

If your headaches are accompanied by confusion, difficulty understanding speech, fainting, trouble seeing, nausea, or vomiting, this may indicate a more serious condition.
