Hi all!

I dive as a biological researcher, which involves a month of intensive diving per year (twice a day, dives usually of over 2 hours each). Every year, I remember that with diving, precordial catch syndrome seems to be aggravated.

Info on that here for those who don't know what it is (I guarantee at least one person will realize that's what the occasional chest pain that panics them is:
Precordial catch syndrome - Wikipedia
TIL that the sharp pain I've experienced since I was a young girl has a name, and not too much known about it: Precordial Catch Syndrome (PCS) : todayilearned)

So, what happens is that about a week into the season, it starts to occasionally occur during a dive, whereas in everyday life, it's only a few times a year thing (it generally decreases with age).

I was just curious if anyone else has experienced this or similar? It's not something that worries me as it is a condition I've had life-long that is not threatening, but it is curious to me that something about diving (and it seems particularly something about diving in the cold) seems to trigger it so much. Maybe something unusual about breathing in those conditions?
