My youngest son has had it for about a week. As of yesterday I now have something as well. Definitely constricted breathing and dry hacking cough. Headaches and chills round out the package for me. I've missed the last two days of work. Awesomeness.
The worst part is, I can't relax and rest without going into a coughing spasm. The cough medicine helps some but the only relief I've found, for the most part, is to sit up straight here at the kitchen table. Yuck.
I've got it too. Whatever it is, it's the worst I've had since as far back as I can remember.
Feeling better, tried a little warm up exercise before going to crossfit & coughed so hard I blacked out for a sec., this stuff sucks.
