Almost exactly a year ago I was hospitalized with strep pneumonia..some of you have probably seen my threads on it. Well, I'm sick again, Monday and Tuesday I had a sore throat, Wednesday I developed a cough, today it's pretty bad and I just feel achy. I have felt perfectly fine with the exception of the sore throat and annoying cough, but this morning I just don't feel right. Tuesday night I started taking a z pack, shouldn't I be feeling better by now? I didn't go see my doctor, just called...fairly certain he had a panic attack when he realized I was sick again. If I'm not feeling at least a little better by Monday I will be calling him again, but if I'm overreacting I'd like to know before I bother him. Pretty much what can you tell me about z packs?
