Thanks for your question on Healthcare Magic. I can understand your concern. Prominent bronchovascular markings are commonly seen with bronchitis (inflammation of airways). And your symptoms like cough, shortness of breath, chest pain etc are also suggestive of bronchitis. So better to consult pulmonologist and get done 1. Clinical examination of respiratory system 2. PFT (pulmonary function test). PFT will not only diagnose bronchitis but it will also tell you about severity of the disease and treatment is based on severity only. You will need inhaled bronchodilator (formoterol or salmeterol) and inhaled corticosteroids (ICS) (budesonide or fluticasone). Don t worry, you will be alright as this is not a serious disease. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
