Yes all of a sudden. I had heat come over my head face and chest got very red. I had difficulty breathing in a deep breathe without coughing. Then i felt nauseous and like i needed to have a bowel movement. I had diariah. And i believe emptied right out. I gagged but didnt actually vomit. The heat gradually subsided and am on the cool side right now. I still cant seem to get a deep breathe w/o coughing and i dont feel back to the way i felt before this came on very suddenly about 20-25 minutes ago. Im kind of shakey. Oh and i almost feel like i have something stuck in my theoat and my chest
