<s>[INST] Hi doctor, when I was about 6 I was diagnosed with mild asthma. I only had symptoms during cold season, and then it eventually went away all together. I am now 18, and during the past year I have been getting chest tightness, low peak flow readings, and wheezing. Some doctors say my lungs are clear and its not asthma, and others say it is? What should I do. I am on advair, spiriva, and ventolin. Please help [/INST] Thanks for your question on Chat Doctor. I can understand your concern. By your history and description, possibility of asthma is more likely. Asthma can recur or reappear in adult life. So better to consult pulmonologist and get done clinical examination of respiratory system and PFT (Pulmonary Function Test).PFT will not only diagnose asthma, but it will also tell you about severity of the disease and treatment is based on severity only. You may need newer ultra long acting bronchodilators like indacaterol and glycopyronium. Chest physiotherapy and deep breathing exercises are also useful. Oral combination of antihistamine (levocetrizine or fexofenadine) and anti-allergic (montelukast) once a day at night is also beneficial in asthma patients.Don't worry, you will be alright with all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
