Man survives flu coma

ARIZONA — He says it was hard to believe, because his son is just 27 and as far as they know, he has no underlying health conditions.

"Strong guy, always healthy, never gotten sick, always been active, hard working and it hit him," Felix Sr. said.

It hit him with a fever of 105, constant vomiting, chest pain and body aches.

His kidneys were even shutting down.

"It's just painful," Felix Jr. said.

Doctors say this isn't out of the ordinary.

They're seeing more and more healthy children and adults in the hospital fighting the virus.

"I didn't think it would hit this hard though," Felix Sr. said.

His doctor released Leo on Friday, but after losing 30 pounds he has to go through physical therapy to get his strength back.
