Since it seems that there are plenty of people with broad health knowledge, here is one for you to solve:
From time to time, at more or less random moments, I get a sharp pain in my chest, more or less where the heart is.
Over time I come to realize, that drinking 1 glass of ( preferably very cold ) water solves the issue immediately.
Sometimes there is no drink in vicinity ( last time was in the train ), so I collect as much spit I can, and then "pretend" to drink.
Sometimes it happens in the middle of the night, and I have to get up to get a drink
It is not a heart attack, ( otherwise I would be dead since a while ) and I don't suffer of high blood pressure.
Curious to see what OZBargain has to say.
seriously, stop being such a p*ssy. Just hold your breath and beat your chest furiously when it happens. It will go away. Be a man, stop asking for advice especially doctors. I mean, what do doctors know, nothing :)
