""It can get into your nose and into your airway, down into your lungs, which will cause you to have more coughing," Dr. Hertz says.
In extreme cases the inflammation and coughing is so severe your lungs could collapse.
That's what happened to Fred Reed's daughter.
"My daughter stayed in the hospital for almost a week and I almost lost her," Reed says."
