About a year ago, Lukas Bengtsson realized something was wrong.
He was used to being constantly tired — so much so that his friends and family would sometimes tease him about it — but, just before he left his native Sweden to come to North America for his first Penguins rookie tournament, he thought it might be something more serious.
He was right.
Bengtsson described what followed as “probably one of the toughest years of [his] life.” It included two misdiagnoses of Lyme disease, a spell in which he was barely able to get out of bed and a stint at the Mayo Clinic in Minnesota.
