Actually most people with migraines significantly improves it/ get rid of it by altering their concious focus.

When ever i get migraines/splitting head aches, i noticed that most of the time im in a very emotional situation where i've either gotten really mad or either i've been really overwhelmed. Every single time i was able to dissapate the pain by simply finding something where i can use my whole mind to concentrate on. And usually that would be finding something to Photoread and activate.
