[|AI|]  Thanks for your question on Chat Doctor. I can understand your situation and problem. From your description following are the possibilities.1. Lower respiratory tract infection (LETI)2. Bronchitis3. Asthma. So better to consult pulmonologist and get done1. Chest x ray2. PUT (pulmonary function test)Chest x-ray is needed to rule out LETI (pneumonia).PFT is needed to rule out bronchitis and asthma.PFT will also guide you about severity of the disease. And treatment is based on severity only. So better to consult pulmonologist and first diagnose yourself and start appropriate treatment.
