A couple weeks ago I had the flu(A). I got over it and then I started to have chest tightness and shortness of breath. They diagnosed me with bronchitis. They gave me steroids and antibiotics to treat it. Let me remind you I am a smoker but I have cut back a ton since I fell sick. I finished my prescribed medications. This morning I woke up with a very bad dry cough. Every time I take a deep breath, I wheeze and cough very hard. I have coughed so hard to the point I have a migraine. It did get very cold where I live last night So I m not sure if the cold makes the bronchitis worse . Also my chest feels very tight and at times my lungs feel sort of Shallow .
