I suffer from barometric pressure migraines. They put me on the couch almost daily. I can feel the pressure change for example from 29.76 to 29.79 and will need a coffee to help. My husband and I got our 2nd Covid vaccination on Tues 4-13. We knew to expect fever, etc the next day and were prepared for that. My husband did indeed wake up feverish and achy all over. But, somehow, the universe knew that I suffered enough on a daily basis and I was given a pass for the day. So, what I want to know is, WHAT is in that vaccine AND can we isolate whatever it is that helped me not be in pain for ONE WHOLE DAY and put that in a daily pill? It was pure heaven! Just thought I'd get that off my chest...and yes, the pressure was all over the map yesterday, so I should have been in pain (I keep notes). Sigh....Tucson is NOT the place to live with this type of headache!
