@Sidoine I do! How interesting that you made that discovery! That is in-sync with mine that HIIT exercising measurably reduces migraine activity.
I'm especially sensitive to migraines due to it presenting as hyperacusis that feeds on my tinnitus. They will end up riling each other up and making my head buzzing and spinning. I've tried all medications, I'm on a migraine diet (and we're paleo, too), I even started doing light exercising every day, but in my fourth year of treatment it still plagues me.
The HIIT exercising shocked me when it first reduced the migraine. I had picked it up to build testosterone at my personal doctor's suggestion. I blend a couple of HIIT exercises into my daily regimen of core strength training and yoga. So it's six days per week, nearly the first thing I do in the morning.
