Under Pressure

I think this might be proof that atmospheric pressure affects migraines. I have been migraine free all month up until about the 21st, when I started feeling the pre-migraine pressure in my head. Then I ended up getting a pretty bad one on the 24th which happens to coincide with an unusally high pressure spike on the weather station.

It may be a coincidence, but the chart definitely fits my theory. I'll continue to map this.
