Is this a heart attack?

So getting to the age where that’s a legit question
Since Friday I’ve had some weird bug (slight nausea, body aches, little appetite- but no fever really)
So last night I got these chest pains (but really I think it was dehydration, actual chest muscle tightness), but I tell ya, nothing gives you a good night sleep like - “is this it? Am I going to have a heart attack in my sleep and my kids will find me dead?”

Fun times

Sounds like a hangover...(and hopefully, that's all it is)

As others have said, check your blood pressure and see a doctor (not a Doc-in-the-Box or a Quack Shack). Blood pressure spikes and fluctuations can do very weird things to the human physiology.
