<s>[INST] Hi there,I suddenly start cough for 3 weeks with sore throat when coughing. I took even one pack antibiotic which did not help. I insisted GP for my chest Xray which he was not happy to send me to saying my chest sound clear. Anyway I insisted and he send me to for Xray. Today I receive result and my GP say it is all OK.However,  result state:There is  hyperinflation of both lungs with flattened diaphragm suggesting chronic obstructive airways disease. There are a few linear vertical densities in the right lung apex suggesting linear fibrotic change.There is no active lesion seen in either lung. No mass lesion or consolidation.Normal heart size with normal cardiomediastinal contour. The right and left pleural spaces are clear, there is no pheumothorax or pleural effusion. [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Your chest x-ray is suggestive of hyperinflation changes. These are common finding in smokers. So if you are smoker then you should immediately quit smoking. And for conformation, you need to get done PFT (Pulmonary Function Test) for the confirmation of COPD (chronic obstructive Pulmonary disease). It will also tell you about severity of the disease. And treatment of COPD is based on severity only. Treatment of COPD is as follows. 1.  Quit smoking as soon as possible. This is the most important step in the treatment. 2. Inhaled bronchodilators and inhaled corticosteroid. 3. Chest physiotherapy and deep breathing exercises to improve lung function. 4. Vaccinate yourself with adult respiratory vaccines like pneumococcal and Influenza vaccines to prevent recurrent lung infection. So consult pulmonologist and discuss all these. First get done PFT. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
