I had a similar issue with the acute HBP out of nowhere and constant headaches. My liver levels were also all out of whack. I never figure out what caused it but it did resolve after several weeks. My BP and liver are completely normal now. The best I could do was narrow it down to recently starting to drink a ton of green tea or some supplements that I had started taking. I just cut it all out and it went away.
