The pain associated with tension headache typically impacts the whole head, but may begin in the back of the head or above the eyebrows. Some people experience a band-like sensation which encircles their skull, while others describe pain as a muscle tension in their neck or shoulder regions. The pain is frequently described as constant and pressure-like. Most people who have a tension headache are able to continue their daily activities despite the pain. Tension headaches are not associated with nausea or vomiting, and do not have symptoms like flashing lights, blind spots, or numbness or weakness of the arms or legs which precede the headache. These symptoms can help distinguish tension headaches from other types of headaches. In some cases, people with tension headache report some sensitivity to light or sound. The pain of a tension headache tends to come on gradually and even at maximum intensity is not incapacitating.
