Hi yesterday I was sent for a chest X-ray due to pain under my left breast top of stomach which I felt was making me a bit breathless anyway I had a call today to visit my gp for results . I attended today and have been told there is some shadowing to my right lung unrelated to my pain . My gp feels I have an infection in the top area of my right lung and prescribed a week of antibotics and a repeat of the X-ray in 6 weeks time . I have no obvious sign of an infection just a mild occasional cough . I am asmathic who did smoke for possibly 25 years . I am not sure what I am asking but should I be worried ?
