The cause of
tension headaches is not clear. In the past, doctors
believed that tension or spasms of the muscles of the neck, face, jaw, head, or
scalp played a role in causing these headaches. Now they think a change in
brain chemistry may also help cause a tension headache.
Tension headaches are the
most common type of headache. They can be
triggered-by things such as stress,
depression, hunger, and
muscle strain. Tension headaches may come on suddenly
The symptoms and discomfort from migraines can go far beyond excruciating head pain. Many people who get headaches, especially those who get migraines, also experience vision problems, dizziness, and vertigo.
