I DO have discomfort in my chest, but only periodically, and only
when staning
up after sitting for quite a while.
When i stand
up quickly, i feel pressure in my chest and head, and my heart beats really, really hard. Not fast, but hard. It goes away after about ten seconds, but it is horribly uncomfortable when it happens. I know that I have orthostatic hypotenison. Could this be the cause of this?
