It is indeed a pity blood tests are regulated, and not available not anyone who wants them -- I would be making millions out of people like you&#x27;d draw bloods before, after, and during migraine, and test for who-knows-what for who-knows-why. I&#x27;m curious, though, how come is that blood tests are not possible during migraine attack, I really cannot understand why should it be so.<p>That being said, you have no clue about human physiology, and not much more about clinical biochemistry.
