I had some sort of bad migraine episode where I couldn't stop puking. Every time I threw up, the force of doing so would cause a wave of pain that was like someone hit me in the head with a baseball bat.
You reminded me of the one time I was visiting my uncle as a child and I ended up puking in the car because the sun was hitting the back of my head in summer, and this was Australian summer where It can get hot and humid
I don't know if it was a migraine but it was painful as fuck
