There are many different types of headaches. A headache .......... as the body's red flag, warning us that there is something wrong somewhere else in the body. Each different type of headache has a different ........ coming from somewhere in the body or the nervous system. Strangely enough, the pain felt ....... a headache doesn't come from the brain itself. The pain is actually from the pain felt ....... the sensitive coverings of the brain, and the large veins and arteries ...... drain fluid from the brain.
Teeth, ears and muscles produce headaches by sending ...... pain to these sensitive covering. When pain gets really ..... the muscles spanning the neck and the base of the skull contract.
The majority of headaches ...... by the widening of the arteries ....... the skull. The best cure is to relax and take it easy. If pain ...... then visit a doctor or a nurse.
