Finally saw the doctor on Wednesday, and he gave me an antibiotic. Today was the first day I could actually breathe! I love Zithromax! I still have a bit of a sore throat, which alternates with a cough (dry and hacking, for the most part). I hope the cough goes away eventually. It's been so long since I've been this sick (since I stopped teaching teenagers!) that I don't know if I'll end up with the lingering cough. Time will tell . . .
