One way to tell it’s a migraine is by the length of
time it lasts. A migraine isn’t going to go away in a half-hour. Unless
you are very, very, very lucky. Chances are your headache, if it truly
is a migraine, is going to last anywhere from four to seventy-two hours.
Yes, that’s right. Seventy or more hours is not common, but neither is
unheard-of. Should your headache last that long, of course, you should
be in the emergency room. Don’t wait nearly that long to seek medical
attention.
A migraine usually isn’t just a
headache. Which is to say that one or more of the following usually
accompanies a migraine: nausea, vomiting, extreme pain, sensitivity to
lights, and auras. It is the aura component, perhaps, that most
especially defines and differentiates a migraine, though, it must be
admitted, some people do suffer migraines without experiencing auras.
Therein lies the difficulty of treating migraines: No two are quite
alike. Another person suffering from their own version of a migraine may
never experience the symptoms you may experience with every migraine.
No
reliable records on the number of people who suffer from migraines has
ever been compiled, but it has been estimated that worldwide the number
of sufferers could be as high as 100 million, though that number is
definitely on the high end of estimations. Migraines are not limited to
adults, either. Unfortunately, many children suffer from migraines.
Regardless of how many migraine sufferers there really are, almost all
estimates agree that two-thirds of migraine patients are women.
Actually,
to speak of a migraine headache is somewhat misleading. In fact, there
are really two types of migraines, the common migraine and the classic
migraine. Although there are differences, both result from the dilation,
or expanding, of blood vessels that had become constricted due to the
release of seratonin. This dilation causes pain in the nerves. Both
types can occur as infrequently as a few times a year or as often as a
few times a week.
The common migraine is the slower to develop
and is often preceded feelings of anxiety, depression or tiredness. In
addition, you may find yourself subject to irritability, sudden cravings
or bouts of unexplained yawning before the onset of a common migraine.
Once the headache begins, a common migraine is almost always limited to
just one side of the head.
The classic migraine develops in a
much more complex way. In fact, there are four stages in the onset of a
classic migraine headache: prodome, aura, headache, and postheadache.
The
prodome stage, like the beginning of a common migraine, may begin with
feelings of fatigue, irritability, or depression. The prodome stage
takes about 24 hours before it slides into the aura stage.
The
aura stage involves an expanding area of blindness caused the narrowing
of blood vessels. The blind area is girdled by a shimmering border that
may increase to include up to half your field of vision in each eyes. In
addition, often there are visual disturbances such as bright spots,
flashing flights, zigzagging lights. Sometimes sufferers also experience
burning sensations or a weakness on one side of their body. Generally,
this stage lasts anywhere from ten minutes to half an hour.
The
third stage occurs when those constricted blood vessels dilate and blood
literally gushes to the brain. At this point the headache as we think of
it really begins with a severe, throbbing pain on one side of the head,
though it is not uncommon for the pain to expand to include both sides
of the head. The pain often gets magnified by bright lights or loud
noises.
The fourth and final stage is the postheadache,
characterized by tiredness to the point of outright fatigue.
Migraines
differ from tension headaches in that tension headache pain tends to
cover the entire head. On the other hand, it’s not uncommon for migraine
pain to be localized not just on one side of the head, but sometimes in
one particular spot of the head, such as at the temple or behind one ear.
