How long do you take off when you have a cough? I got sick and it started in my throat but now it's a full blown sinus and respiratory cold. I'm coughing but not much, more in my sinuses. I was in pretty good shape but now I am hesitant to run because it's a bit in my lungs now and I am prone to pneumonia. The kid I got it from is still coughing so I don't want it to turn into that. How long would you take off?
