| tension headache | <neurology> A benign form of headache that results from the painful spasm (muscle tightness) and inflammation of muscles of the head and neck. Tension headache is one of the most common forms of headache. Spasm and contraction of the head and neck muscles may occur in response to fatigue, overuse, eye strain, excessive smoking, stress, anxiety or depression. Sleeping in an abnormal position or prolonged work involving immobilisation of the neck in one position (typing, computers, etc.) are considered common triggers. Exercising and stretching the muscles of the head and neck can reduce the occurrence of muscle tension headaches. (13 Jan 1998) |
