<s>[INST] hi, I am 51 years, 5 feet six and a half inches tall having weight 72 kgs, my x-ray report says broncho-vascular markings are prominent on both sides. Blood test report is normal. I am suffering from dry cough while expiration. No relief with antibiotics and cough syrups. Can you guide me. [/INST] Thanks for your question on Healthcare Magic. I can understand your concern. Prominent bronchovascular markings are commonly seen with bronchitis (inflammation of airways). And coughing while expiration is also seen with bronchitis due to bronchospasm. So better to consult pulmonologist and get done clinical examination of respiratory system and 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 mostly improve with inhaled bronchodilator and inhaled corticosteroids (ICS). Don't worry, you will be alright with all these, consult pulmonologist first. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
