Coughing in my bedroom...?

For the last few months, when I am in my bedroom I cough.. alot. Its starting to get really painful. Sometimes the coughs are dry, sometimes they are not.and i always feel like i need to clear my throat. I'm not sure what to do. Its weird because it only happens in my bedroom and i cannot figure out what is causing it.

Now, even though the coughing doesnt happen much outside of my room, I am beginning to have other health issues. Fatigue, no appetite, chest pain, heart burn etc.. and they all seem to be getting worse.

I know i should go to the Dr. but I just started a new Job and my insurance has not started yet, so I am trying to wait for that because if there is something actually wrong with my lungs i dont want to wait till the coverage starts.

Any thoughts on what could possble be causding my symptoms?
