I had a call yesterday to a 22 y female with Hx sinusitis after brief LOC on the way to the restroom. when we got there she was alone in the house in bed. VS was not alarming and we transported her to the hospital for treatment. after advising the triage nurse she was directed to wait and we were released. later that afternoon we were back in that ER and were told that she had a tony colony sizer do to her Hx. i wanted to know how sinusitis can cause that.
