Question: I am 55 years old, non-smoker, white male, 190lbs 6'4", athletic. While on vacation over a month ago, I got pain in my left (non heart side) ribs about four inches below my arm pit. It got worse and worse until every breath was so painful, that I had to sleep sitting up in a chair. I had NO cough and no cold symptoms, but did cough up two small mucous with some blood in it. The pain was so bad I went to the ER and they did a CT scan and x-rays. The said that I had pneumonia in the right bottom lobe and gave me antibiotics. That got rid of the pain in a day and a half, but it lingered after I finished the antibiotics and so when I got home, my GP gave me another antibiotic Levofloxacin 750MG and another x-ray with till showed a small somewhat linear airspace opacity at the right peripheral lung base, but lungs are clear and well expanded. Now two weeks later another round of x-rays and the opacity has not changed. He would like me to come back to check again in three months. The radiologist recommended close follow-up and if "this lesion continues to persist despite adequate treatment, the possibility of an underlying lung nodule should be considered and a CT scan may be beneficial." My question...what do you think is going on here? I fell good now. Some slight pain if I take a huge breath and kind of twist my trunk a bit. I am a cyclist. No problems riding at training speeds. This has me worried. Can you shed some light?
