I can relate to this perfectly.

Last year I had four scares with a sudden onset of a racing heart combined with light-headedness, cold sweat and sudden chills. Three in my home country and one during a business trip to Xiangyang.

In the first three instances, I called the nearest hospital and admitted myself to the emergency department where the doctors did blood tests, MRI scans and X-rays. And the answer was always "We don't see anything wrong with you!"

Finally on the fourth scare the doctor asked if I consume tea, coffee, energy drinks or colas. When I responded positively, he put me on a lifetime ban of these drinks on suspicions that I am having an adverse reaction to the caffeine in them.

Since I never had any more episodes for the rest of 2019 I thought that was indeed the case until I had another incident in February this year. And as expected, the doctors were unable to determine the cause since caffeine was definitely not involved this time...

I see the problem. They didn't scan the main body.

They're probably checking to make sure he didn't have a concussion or stroke.

djseifer's joke is that they scanned the humanoid part of Kogasa, not the umbrella.

Not to mention that it's probably a spiritually related disease, so best find a witch doctor or a shrine maiden.
