<s>[INST] I feel warmth radiating in my chest area. It does not bother me to take a deep breath. the warmth is felt above my breast bone. Thanks! But I think I will go to the local Doc. My insurance covers the bill and I am not sure if you are real or just someone looking to make a few bucks. [/INST] Thanks for your question on Chat Doctor. I can understand your concern. Warm feeling in chest area is commonly seen with early lung infection and bronchitis. So in my opinion, you should definitely get done chest x-ray and PFT (Pulmonary Function Test). Chest x-ray is must rule out lung infection. PFT is must for the diagnosis of bronchitis. If both these are normal then no need to worry about lung infection or bronchitis. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks. </s>
