Conversation: The conversation between human and AI assistant.
[|Human|] I recently visited a friend who complained of chest tightness and shortness of breath in the afternoons and early evening. He stated he had no difficulty breathing at night or first thing in the morning. His doctor just called him in an order for antibiotics. He has no cough or congestion. What do you recommend? He is 62, retired from department of transportation and the navy sea bees.
[|AI|]  Thanks for your question chest tightness, shortness of breath, allergy to dust and smoke, cough can be symptoms of asthma and in this age it can be a late onset asthma other diseases can be heart related like ischemia you need to visit a pulmonologist and a cardiologist who can request for a chest X-ray, spirometry, an ECG, and he can examine you in detail and will rule out uncertain causes thanks feel free to ask more questions may god bless you with good health
