Hi My Question Is I Went To Hospital Sunday Night.

hi my question is I went to hospital sunday night. the Dr. asked me what problem was. I told him for about ten days I was coughing up dark green sputum so thick I would throw up. he said it sounded like bronchitist sp. wrong. he asked me if I wanted a x-ray? I said I don`t know what did he think? He said it`s your body you should know if you need one. He listened to my lungs. He then said that he would write me a script and give me a breathing treatment and antibiotics that I should feel better. Ieft the hospital and went home.
woke up in the middle of the night with severe pain, felt like like it was on the upper right breast. Not sure if thats in the lung or what. What do you think and what so you think )I should do.
