For the last week or so I’ve been awaken in the middle of the night by severe chest discomfort, almost pain. My family physician checked my heartbeat and ordered me to have EKG done, but she thinks that the pain is not related to heart. It doesn’t radiate toward my arms and, like I said, it happens only at night when I wake up feeling like I have weigh on my chest together with excessive sweating. I’m male, 40, and have been generally healthy up to this point, so I was wondering does anybody have any idea what might be causing this chest discomfort at night, other than heart issues?
