I found the cause of my debilitating and almost-daily migraines for 15+ years, when I had a stroke that left me with numerous permanent disabilities.
I've talked to a couple friends who also suffer from similar ones and neither had been to a doctor recently. I now tell everyone to check their bp and for fucks sake see someone about it, don't just pop 2 pain pills and lay down. You may be relatively fine, but you don't want to turn into me. My life ended that day.
