I wanted to add that for some reason for us adults, it has been coming and going. Meaning that we will have one or two days where it feels like it is gone and the next day it comes back full force. The teenagers, however, have had it non stop for over a month (this is why they have had it longer than us). Maybe that is why it is more likely to put teenagers and young children in the hospital. But, they don't have the physical pain we do.
