It is chasing, because, once this headache
starts, it occurs daily over a period of weeks extending up to several
months! Then it may suddenly disappear and dramatically reappear during
the same season in the ensuing year. Its timing is marked and it is
perfect!
Who is or what is responsible for this cluster
headache? Nothing is known for certain. But it is reasonably proved that
changes in the walls of blood vessels in the head have a role to play in
the advancement of the cluster headache!
Brain by itself is a non-committal entity. It feels no pain. The pain of
headache comes from the tissues surrounding the brain, the attaching
structure at the base of the brain. The muscles, the scalp vessels, the
vessel of the face and neck, may cause cluster headache. Or it may be
specifically to blood vessels dilation or to inflammation of nerves
behind the eyes.
The pattern of cluster headaches is very interesting.
There are active periods and passive periods. Headache occurs in
clusters. It may be days, weeks or even months, during which headache
bothers you in clusters, every other day or ten times during a
particular day. Head-ache free intermission may last for several months
and years.
During the active period, you have to be careful about
your lifestyles and discipline. Attacks may be triggered and intense
suffering may bother you. The reasons may include: intake of alcohol,
going to a place of high altitude, air travel, intense heat due to
sunlight or due to any other reasons like taking of those items of food
which are high in nitrates and many more.
Since cluster headaches are a serious type of headache, you have to
budget your day, in all its aspects according to a strict schedule, that
is suitable to you. You only know it by past experience, what is
suitable for you!
