I had a car accident last year and the Dr never mentioned anything about my chest x ray showings. Upon reading the report today. The radiologist report shows: biapical pleural thickening, perihilar interstitial prominence, mild hyperaeration. I don't even know what any of this means. I haven't had any symptoms until recently I started coughing up phlegm and I got short of breath walking up a flight of stairs but it subsided quickly. Aside from that I'm healthy. Need to ease my mind and anxiety.
