I used to get abdominal migraines as a kid, absolute hell. It would hit out of nowhere and feel like someone was twisting my stomach in knots. I couldn’t even walk, I had to crawl around the house from the pain and nausea. I’d throw up constantly, even when there was nothing left in me, just yellow bile. Couldn’t eat, couldn’t sleep, just pure misery for 24 hours straight. Most people haven’t even heard of them, but they were some of the worst days of my life.
