But yeah~ what a nasty bug !
First noticed a VERY sore throat Sunday, and by Monday my (our) entire head was pumped over full & eyes ready to pop out & PAIN down the back the neck...and you know the rest.
Einstein was extremely hurt by eye pain, and back of the neck pain...it went in my lungs, and I have been hacking to the point of passing out.
He has not had this happen.
