Sounds like a serious attack of the whoopsies.
Probably a couple of dozen possibilities!
When they've done smoking and drinking and can't think of anything to say, they'll be on about losing weight, drinking more water, and all that. Probably would be appropriate for half the forum...
We'll all be guessing from anecdotal experiences -
They'll have done a CRP check to see if there's any infection, like a Urinary Tract thing which can have surprising consequences, like you had. My inlaws kept getting those, with similar events.
If you have any heart history I'd suggest you ask for an "echo" , an echocardiogram. It's just ultrasound but gives a pretty comprehensive check. If my wife had had one earlier than she did, she'd still be alive. Takes half to one hour, painless. They're reassuring to have had, and
GP's can't just call them up. They might put you on a treadmill at the same time looking for BP dips and all that.
If they can't be sure, they may send you home with a Holter Monitor, you wear for a day or three which checks things like heart and BP.
Hope you can get some sleep. You'll know you're doing OK if they let you have breakfast, so good luck for that. Everything's brighter after breakfast.
If you fail to tell us all about it, you get Reported, OK?
