Hi, I catch cold and cough every month. And experience difficulty in breathing if I talk for 30 minutes continuously or climb the stairs or after a 10 minute walk. Done a CT thorax as per local pulmonologist advice. He said nothing much to worry. Please advise. The CT report impressions were as follows: * Focal subpleural fibrotic opacities in the medial segment of right lung middle lobe. * No significant mediastinal lymphadenopathy. * Minimal bilateral pleural effusion.
