About 3 or 4 weeks ago I started to have this cough. It seemed to be worse at night while I was laying in bed. My dad suggested that I might have mold in my house, so I went to stay with a friend, that didn't help any. I haven't felt sick AT ALL!! Other than a sore throat, from coughing so much. I have been taking an off brand cough medicine that has dextromethorphan in it, and the cough isn't going away. However, it wasn't getting any worse until this weekend. It was staying about the same, then all the sudden Friday it was like I hit a brick wall! It's gotten worse and worse all weekend and yesterday, all though I didn't feel sick to my stomach, I thought I was going to vomit several times from coughing so violently. This morning I feel like I have 100 pound weight on my chest and it hurst to even breath, and the cough is still here. I've called my doc, but I can't get in for over a week. Help?!
