<s>[INST] I have a lingering cough not wet. My chest hurts a little and I dont feel like ever take a deep enough breath to cough only once. My head feels like exploding with every single cough. I am not congested in my nasal or sinus passages. I will guess I have been coughing aboit 3 weeks or so. Is there anything serious going on or will it pass. I do have a dr appt on march 6 [/INST] Thanks for your question on Chat Doctor. I can understand your situation and problem. You are having chronic cough (cough for more than 2 weeks). Lung infection and bronchitis are common causes for such chronic cough. So better to consult pulmonologist and get done1. Clinical examination of respiratory system 2. Chest x-ray 3. PUT (Pulmonary Function Test). Chest x-ray is needed to rule out lung infection. PFT is must for the diagnosis of bronchitis. You may need antibiotics, antihistamines, inhaled bronchodilators and inhaled corticosteroid (ICS) according to the diagnosis. Don't worry, you will be alright. But first diagnose yourself and then start appropriate treatment. Hope I have solved your query. Wish you good health. Thanks. </s>
