hey, thankyou for your quick reply!
I went to the doctor today, and she said that my chest sounded quite clear (I felt better today, and ddint feel as if there was any stuff in my chest), and she said that I prob had a really bad cold/virus, and that it was taking a while for me to get over it. She also was asking me if I was wheezing and stuff, and I mentioned I had asthma when I was small, and she pruscribed me an inhaler to take at night for the coughin/tight chest. She also said if the tight chest gets any worse or persists to go back and see her!
I'm relieved that my chest seems clear. I think I must have had some kind of infection in my lungs, and its cleared up!
hope your pneumonia gets better soon, and hope you feel better!
