There are various types of headaches:
Tension
Symptoms: A dull, steady
pain that feels like a band tightening around your
head
Tension headaches usually bring on neck and
muscle discomfort.
Cluster
Symptoms: A nonthrobbing pain around one red,
watery eye, with
nasal congestion on that side of your face
Cluster headaches come in groups over a set period of time. Nasal congestion and a flushed face may accompany the headache.
Men suffer from this kind of headache more than
women.
Migraine
Symptoms: Throbbing, begins on one side, and causes
nausea or sound or light sensitivity.
Visual disturbances, such as flickering points of light, may precede the headache.
Before many migraines, the victim will experience an
aura (a warning of the migraine coming). The victim may also experience
nausea and
vomiting.
Sinus
Symptoms: A steady pain in the area behind your face that gets worse if you bend forward and is accompanied by congestion
These headaches are caused by
inflammation and
infection of the
membranes lining the sinus cavities.
