Post whiplash headaches or cervicogenic headaches (literally headaches
from the neck) appear to have a few different causes. First, the
straightening
of the neck can cause the head to move forward and this can irritate some nerves at
the back of the head. These nerves, the greater occipital and the lesser occipital,
can then cause headache. There are also
joints in the upper part
of the neck (C2-C3) and in the jaw that can refer pain to the head. Finally,
areas in several muscles can develop trigger points which can
refer pain to the head. |
