Bless you, O'N', for somehow keeping a sense of humor about this, and for the good care you have taken of yourself.
At the same time, this guy should be reported to someone. He's a disgrace. It's one thing to be ignorant about CH (as so many are), it's another thing to have your head this far up your butt that you can't see daylight. In the great journal article posted here recently (https://www.bmj.com/content/376/bmj-2020-059577), this appears on the first page. Maybe you should send it to him. Or someone.
Sex ratios and cluster headache
The true sex ratio is unclear, as the sex ratio decreased each decade from the 1960s to the 1990s at a single site, and the male to female ratio was 4.3:1 in a 2008 meta-analysis but 1.3-2.6 in large studies in the 2010s. Previous misdiagnoses in women are one possible reason for the decreasing sex ratio.
