Coughing up a lung

I have bronchitis on top of a sinus infection on top of a severe asthma attack. Also running a fever over 100 since Saturday. Doc gave me an antibiotic, prednisone, and instructions to hit my asthma inhaler 4 times a day. I stayed home from work Monday and Tuesday, but am braving work today. I had to go for ultrasound and bloodwork this morning anyway. Plus my Follistim refill was being delivered to the office and I need it for tonight's injection. Maybe I'll just go home now that it's been delivered. I feel completely like crap.
