question: female age 46, non smoker, social drinker, no previous health problems, exercise regularly, not overweight I have been having pressure in the chest for over a month with a little tickle in my lungs but no cough. No fever but tired feeling all the time. Went to my doctor and he did an ekg and lung function test (where I blow through a tube). He said everything looked fine but was a pattern of allergic breathing? so told me to take Claritin for a couple of days. Nothing improved so I went back to my doctor and he gave me Dulera to take for a couple of days. Still no improvement. I am guessing I need a chest x-ray next but any idea what it could be?
