Yesterday at an urgent care clinic i was diagnosed with a bad case of bronchitis. I'm having a very hard time breathing. I'm using the inhaler they gave me along with the meds and a vaporizer. I am coughing up very little mucus, one bit had the consistency of fried bacon! About half an hour ago i noticed something different. Suddenly I feel like there is something around my throat, squeezing. What's going on? What should I do?
