I had a severe choking experience this evening on liquid; I could barely breath for about 2 minutes as the liquid expelled from my nose and mouth. After gaining my breath back, I had the expected cough; but that was all. About 2 hours later, I m shaking uncontrollably from freezing, so I went home and took a hot shower. Still freezing after that, I laid under 2 comforters and a heating blanket. Now I m too hot. I m also experience palpitations, wheezing and coughing. Can you help me figure out what I ve done?
