- I had corona last week so they think it comes from there.

I got pressure on my chest after a workout on Tuesday and thought it would let go but it lasted for half an hour, Gunnarsson says to Radiosporten.

The pain increased after the workout.

- I got big pains in my chest, hurt incredibly, when I sat in the car and had to go to the ambulance to the hospital after they picked me up at home.

I had to go home but had to come back and do new tests and then they discovered that it was a pericarditis, says Gunnarsson who was ordered to rest for three months.
