It may be a while before Isaak Lasson's parents buy him another Lego set.
The Salt Lake six-year-old, who has suffered from mysterious sinus problems for the last three years, recently discovered the source of his discomfort — and it wasn't just post-nasal drip.
Turns out, the little guy had been living with a rubbery Lego wheel jammed into his nostril.
"I felt so bad," Isaak's dad told KSL.com. "He was sleeping with his mouth open, trying to breathe."

Multiple doctors failed to find the source of the problem and suggested antibiotics as the remedy.
It took a keen-eyed specialist to see the light — or, rather, the wheel — at the end of the otoscope.
The doctor spotted the fungus-covered tire in July and pulled it out. Isaak's condition has improved dramatically since the foreign invader was removed.
"I asked him, 'Dude, how did that even get in there?'" his father said. "We think he bent it in half — it's pretty flexible — and that it opened up once it got into his sinuses."
Like most young kids, Isaak felt his nasal cavity would make a terrific storage unit. Unlike most kids, however, he forgot he had put it there.
And while his shaken up parents question how this could have gone on for so long and whether they did enough, the youngster is taking it in stride, telling his dad, "'I didn't even know . . . this is weird."
While a Lego wheel certainly figures among the more unusual non food-related items pulled from the tiny cavities of our smallest citizens, the Buzz compiled a list of inanimate objects Toronto doctors have had to pull out of small noses during their ER tenure.
Among those with the highest "ick" factor: safety pins, buttons, Toonie-sized coins, decomposing peanuts, nails, a toy airplane and a Monopoly piece.
