| 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) |

| compartment syndromes | Conditions in which increased pressure within a limited space compromises the circulation and function of tissue within that space. Compartmentation involves mainly the leg but also involved are the forearm, arm, thigh, shoulder, and buttock. Some of the causes of increased pressure are trauma, tight dressings, haemorrhage, and exercise. Sequelae include nerve compression, paralysis, and contracture. (12 Dec 1998) |
