What are the symptoms of tension headaches?

Tension headaches often begin in the back of the head and upper neck as a band-like tightness or pressure. Tension headaches also are described as a band of pressure encircling the head with the most intense pain over the eyebrows. The pain of tension headaches usually is mild (not disabling) and bilateral (affecting both sides of the head). Tension headaches are not associated with an aura (see below) and are seldom associated with nausea, vomiting, or sensitivity to light and sound. Tension headaches usually occur sporadically (infrequently and without a pattern) but can occur frequently and even daily in some people. Most people are able to function despite their tension headaches.
