I woke up yesterday after some really bad, sharp pain in the left upper side of my chest. I quickly walked to the bathroom, where I collapsed and lost consciousness. My girlfriend came in seconds after she heard me drop and saw me trembling on the floor with my eyes and mouth open. After about 30 seconds, I regained consciousness with no recollection of collapsing and a bloody lip from biting it. I went to the hospital and they ran a cat scan, EEG, and blood tests, but said there was no sign of epilepsy. (nothing was wrong, except a slightly high White blood cell count).
This is the 3rd time I have feinted/loss consciousness, and the 2nd time I was trembling, etc during it, but this is the 1st time with severe chest pains.
I am 19 years old, male, 6' and 82kg. Could this possibly be a heart attack? If not, what?
Thanks for your help
