Explain the term - Muscle Contraction Headache
This is one of the most common headaches. It is also known as tension or nervous headaches. They result from sustained contraction of the muscles of the scalp and neck caused by constant stress and tension, especially if poor posture is maintained for any length of time.
Patients describe their pain as steady, nonpulsing, tight, squeezing, or pressing or as the feeling of having the head in a vise.
Some patients complain of a crawling sensation. The headaches may be accompanied by anxiety, dizziness, and bright spots in front of the eyes.
In some people, caffeine may exacerbate the headaches, presumably because it exacerbates anxiety.
