Good morning and welcome to Mayo Connect.

I'm going to ask some questions, and see if we can find others like you with whom to chat. There are so many issues that can cause this, it helps to have a starting point. When you talk about being able to bring up phlegm (mucus) it makes me think there may be an underlying condition in your lungs.

When you report this has been going on for two years, have you seen a doctor for it? Did it come on suddenly, as part of an illness, or seemingly out of nowhere? Do you have any other longstanding medical conditions?

Sue
