Migraine headaches are said to be one of the most common health concerns seen in emergency rooms and family physcians’ offices. It is thought that around 15% of the population suffers from migraine headaches. Women are three times more likely to suffer from migraine headaches then men. Most who suffer with migraine headaches have other family members who suffer as well.
Migraine headaches usually occur on one side of the head. The pain is typically a pulsing pain. Migraine headaches can also occur with vomiting, nausea, sensitivity to light, sensitivity to sound. Usually these symptoms become more intense with just basic routine activity.
Some migraine headache sufferers deal with them on a daily basis while others may only see a few each year. Every person’s migraine headaches are experienced differently.
Migraine headaches can last anywhere from four to 72 hours.
What causes migraine headaches?
The exact cause of migraine headaches is still unknown. Doctors have classified migraine headaches as a vascular headache. This means that the pain of a migraine headache is caused by blood vessel dilation. The vessels swell which causes the nerves that are wrapped around the vessel to stretch. When the nerves are stretched, they release chemicals. The chemicals cause pain, inflammation which causes the vessels to continue to enlarge.
The chemicals that are released are naturally found in the brain. They are dopamine and serotonin. During a migraine these chemicals are found at abnormally large amounts and can cause the vessels to be abnormally sensitive to them.
About one-third of migraine headache sufferers have auras. An aura is usually described as a pins-and-needles felling in the face, hands or arms. It can also be described as seeing spots, flashing lights or wavy lines.
The aura acts as a sign, that a migraine headache is coming. Usually, the aura happens about 30 minutes prior to the start of the migraine.
Some migraine headaches are able to go away on their own. If the migraine headaches are becoming increasingly more common, a doctor needs to be seen. They can treat migraine headaches with a preventative medication or medication that is only taken when an attack comes on.
