I am having severe chills, but no fever. temp is 97.8, pulse is 82bpm, oxy is 97. I am also vomiting, and wheezing badly, and get very dizzy when I stand. The onset of these symptoms was very sudden, it started about 2 hours ago. I have acid reflex issues, and I had my gall bladder out a few months ago, I am wondering what this could be.
