Has anyone out there with classic migraine noticed a connection with trumpet practice? My 13 yr old son, a talented and self-motivated trumpet player, is having a devil of a time with classic migraines (the kind with initial vision changes, then excruciating headache for about 10 hours). I've noticed that of his last dozen episodes, probably half have begun about 15 minutes after he begins to practice. And no, he's not trying to get out of practicing - he loves to play, and is very good at it. The latest theories of migraine seem to link it with stimulation of nerves in the face, so it isn't as crazy as it sounds to think that trumpet practice could be triggering his migraines. Anyone out there ever experienced this?
