This spring I inhaled some sawdust and crap while doing some work on my house. A few days later I started having trouble breathing, and I had a really bad cough. After a few days I called my doctor's office, and they gave me an appointment right away with a doctor I hadn't seen before because I was having trouble breathing. I told him I inhaled some crap while working on my house, but he didn't seem too interested in that. He asked me a bunch of questions, listened to me breathe, and concluded that I had seasonal allergies. Put me on drugs and gave me an inhaler. Didn't help. I gave it a chance for a couple of weeks before I made another appointment and saw my regular doctor. She prescribed antibiotics and within 5 days the cough was gone and I had no trouble breathing.
