I've had a cough for 40 days now, It seems to be getting better but I'm not sure? It's worse in the cold or air conditioning, great in the heat. My doctor has tried an inahaler, azithromycin, prednisone, claritin, prilosec & even a chest x-ray (which came back normal). I really don't have any other symptoms except it occasionally hurts to swallow (more on the right side of my throat) and I also have some drainage from my head and down my throat. Thanks!
