No idea about the aspirin, but a neurologist where i used to work was trying
putting his patients on highflow oxygen for a couple of hours, if they
presented to his clinic during a migraine episode.
Presumably this would have a vaso-constriction effect.
So, either it constricted the vessel that was dilated and triggering the
pain, or maybe the overall vaso-constriction would releive the localised
effect of the constricted vessel.
Either way, it didn`t seem to work any higher than placebo (by my own
observation), but it was worth a try.
