It may be a fair guess that every person has suffered the discomfort of a headache. When it comes to painfulness, the common, ordinary headache does not even begin to compare to migraine headaches. In fact, I used to have migraines when I was very young but they stopped. I no longer have them, but I can inform you they are enormously painful experiences. There is much to be figured out about migraines because they aren’t understood by researchers. There are many reasons for this not the least of which is people can perceive and feel pain in distinct ways. But that is only one small part of a large and complex picture.
