"On a pain scale of one to 10, it was a 10," Scott Shirley recalled. "The worst pain I've ever felt."
It was June 2020, and Shirley, a winemaker in Paso Robles, California, knew something was terribly wrong. He was going about his daily business when he doubled over with severe abdominal pain and a 103-degree fever. A doctor in the emergency room told him his left lung had collapsed.
But what ailed Shirley, now 50, wasn't COVID-19: It was valley fever.
