I spent nearly seven hours in the Emergency Room yesterday, with what at first appeared to a heart attack but turned out to be....well, they don't know. Possibly lingering effects of whatever I had last week. Clear chest X-ray, nice EKG, no weird heart-attack enzymes in my blood work.
We're not going to play doctor, so I won't bore readers with a list of symptoms. (I loathe the kind of "amateur doctoring" many people indulge in, so comments are off and that does not mean you can go to another post and comment. Look, if medicine was that easy, it wouldn't pay so well.)
Other than intensity (often quite lower for women), it was a good fit to a heart attack and I will be following it up.
