There was an article in the FB group about Takotsubo.

I experienced that between the night on 9-10 of January.

I had fallen asleep on the sofa watching TV and woke up round 1 AM and went to bed. But then I first had tooth ace on the left side that moved to the whole side of the left jaw. Then it moved to the neck and to the upper chest.

I was not really a pain, more like discomfort so that you could not sleep.

So I waited awake for the feeling to go away. It just kept going so for some reason I thought of Googling the symptoms of hear attack and it was a match.

In the hospital, the first blood sample showed heart enzymes gone up. The normal level 0 and maximun level 2. Mine was at first about 250 and a couple of hours later over 2600. 
Heart attack levels are between 1000-2000 I was told. So mine was quite high.

The ultrasound did not snow anything wrong with my heart but when it was checked for the 3rd time by another doctor, she asked if I have experienced a shock lately. I had just the previous Saturday. Also later I understood the stress I have been having for the past 3 years + the lost of 6 pets in just 1.5 years. The shock I had a couple of days before was losing another pet quite the hard way.

After the 3rd ultrasound they also did an angiography and found nothing physically wrong with me, so they asked again about the stress and/or shock. 

There are about 200 similar cases like this in Finland every year. 

Is there anything you wish to know more about this?
