Keep in mind that I'm very new to SPQ but I have experienced literally a couple of migraines in my life, so I can empathize. I hardly ever get any headaches at all. But since I'v been sporadically practicing SPQ, on the rare occasions that I feel a headache just coming on, I just imagine my sword fingers are miniature and in my head making chopping motions toward where the pain is developing and the pain disappears. So when your husband even suspects he's getting a migraine, if he does that right away it might work. I hate to ask this though...have they taken any cat scans??
