I can understand your concern. Possibility of either inertial lung disease (OLD) or bronchitis is more in your case. Both are common in acidosis patients and both cause breathlessness on exertion. So better to consult pulmonologist and get done 1. Clinical examination of respiratory system 2. HRC (high resolution CT) thorax. 3. PUT (Pulmonary Function Test). HRCT is must for the diagnosis of OLD. PFT is must for the diagnosis of bronchitis. You may need inhaled bronchodilators and inhaled corticosteroid (ICS) and anti-fibrotic Chat Doctor.  So better to first diagnose yourself and then start appropriate treatment. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
