Tension : Tension headaches are band-like headaches that are usually dull, not throbbing. They are caused by excessive contraction of muscles in the neck, temples and forehead. They are sometimes bad enough to be accompanied by some nausea. They are distinguished from migraine which also causes nausea by the fact that in migraine there may be sensitivity to light and sound and the pain is throbbing and usually one sided.
