I have had hoarseness and quite a bit of phlegm for a month or so and it is not going away?

it would be a good idea to see a dr, he/she could get you a chest xray and prescribe something to help you breathe. in the meantime you can get over the counter something like mucinex, it breaks up the phlegm to help it all come out of your lungs. also , take hot showers and breathe in the steam that helps, and you can use the vicks vapo-rub on your chest/neck when you sleep it helps too. ;)
