I feel your pain. I'm on my second round of steroids to battle asthma right now due to allergies. In fact, my doctor called me in yesterday morning because I was having an attack that my rescue inhaler wasn't touching. He did chest x-rays because he heard crackling in my lungs and wanted to be sure I hadn't developed pneumonia just to add to the fun. Fortunately, just really crappy asthma right now, so I'm on several more aggressive inhalers now and actually feel more human today. This is concert week for me (Elgar's Dream of Gerontius), and I'm trying to get enough voice back and rid myself of the coughing so I can perform. Rehearsal last night wasn't too terrible, so I think I'll be in decent shape by Friday night. Orchestra rehearsals tonight and tomorrow night, so hopefully I'll be in good shape.
