I have had a persistant cough for several weeks now (no sore throat.. Unless it gets sore from me coughing too much). I had a bad cold near the end of july... It went away in the usual fashion after a few days, except i've been left with this persistant cough. For a while it felt like a ball of phlegm was stuck deep in my throat, and the cough would make it distribute, but I couldn't cough it up, and a few minutes later it was back in the same place. I've used zpak (single does oral antibiotic) after seeing a doctor, and while it seems to have gotten rid of the phlegm problem, I am left with the cough... Completely dry now. It seems to go away while I am sleeping completly... And doesn't come back until a couple hours after I wake up and start going about my day (i.E. It seems that laying down for a while seems to make the cough go away for a while until I get up and about again). By mid day the scratchy itchy feeling in my throat causes me to cause almost constantly unless I sip on some water or a cough drop. It's really annoying and kinda embarassing to have this continue on day after day. I don't really want to continue throwing money at doctors (my health insurance plan isn't very good). Any ideas?
