my husband and I both came down with the same symptoms yesterday, almost at the same time. scratch throat (very scratchy), headaches, light headed, at times relentless coughing, and my husband says his body aches, mine doesn't feel as bad. I feel if I could get rid of the scratchy throat, I'd feel better. the temperature here changed from 50's & 60's to the 80's. some wind. what could it be?
