After that, the cough got worse and I developed a sinus infection and
. After a week of that, I finally went to the Dr. when my neck got stiff and
the back of my head started to ache. I was put on antibiotics that helped with the sinus infection but still a cough, aches, stiff neck, and pain at the back of my head. Also, incredibly tired. I have tried to switch to a new pillow which hasn't helped.
