cobalt, Ideas needed for heat triggered headaches. Online all I can find is test, hydrate and maybe an OTC pain med. My son and I are really suffering from it last two days. At least we’ve kept the migraines at bay but they lurk. Last night I was close to heat exhaustion: dizzy, heart rate up. Apparently it gets in via barometric pressure and sinuses. Our home is well air conditioned! At noon 115° outside. #Headache #HeatWave #Arizona #Phoenix
