Barometric Pressure

Someone posted this on a forum that I read:

"Barometric pressure is the measure of the weight of the atmosphere above
us.In fact, it can change how well some people feel.

Measurement of barometric pressure is accomplished with the use of a
barometer. A barometer measures the weight of the atmosphere per square inch
(pressure) and compares it to the weight of a column of mercury.

S... et al. note that low barometric pressure is associated with changes
in cerebral blood flow, increased risk of rupture of intracranial aneurysms,
premature labor, changes in the norepinephrine metabolite HMPG (at least in
women), and changes in cerebrospinal fluid concentrations of the serotonin
metabolite 5-HIAA in people with depression.

The researchers hypothesize that "barometric pressure may alter the
propensity toward impulsive behavior through changes in brain monoamines or
cerebral blood flow."

Pressure doubles every 10 metres down under water. I haven't dived since I got chronic migraine but I'm sensitive to weather changes - this la nina cycle is wreaking havoc (but I still love the rain better than the years of drought!).

I wondered if any of you who are sensitive to barometric pressure have also scuba dived and if so if it sets you off. That's a pretty instant change of pressure over a period of about an hour. Also, I recall trekking over the top of Thorong-La Pass on the Annapurna circuit in Nepal's Himalayas and oh. my. god. the migraine I got then still hasn't been beaten. Huge vomiting monster 5.5km up on the roof of the world. Nice. And then I had to keep trekking with it because I couldn't stop because of brain edema! Fun. Beautiful place though - I wouldn't hesitate to do it again actually.

But I'm thinking about scuba diving because I live in Queensland and would like to do something with it again. It's so beautiful and fun - wondered if any of you have experience with the pressure changes?

I haven't been scuba diving for years, and my migraines were only occasional back then. I don't remember any problems. Now I live at 10,000 feet above sea level in the US. No migraines at first, just difficulty breathing. I took diamox for a couple of months. I'm having more migraines now, but then I usually do in the Spring and Autumn.
BTW, I lived in Sydney for 7 years and did make it up to the Great Barrier Reef, but I snorkeled.
