Conversation: The conversation between human and AI assistant.
[|Human|] Hi, I am a 45 y.o male in good physical shape. 4 weeks ago, I started having a feeling of where I could not catch a deep breath. I went to my PCP who ran all kinds of blood work but found nothing wrong. Was referred to cardio where my stress test and echo were non- eventful. I exercise regularly and have a good diet with no remarkable health issues. Non-smoker, non-drinker, no meds. I started taking Benadryl and Claritin and had some good results for a week and a half. Besides the obvious of going to a pulmonary specialist, any thoughts or suggestions. Does this sound like asthma or possibly Valley Fever? What else should be R/O?
[|AI|]  It does sound like an obstructive lung disease like asthma. But Asthma is mostly associated with cough, breathlessness, wheezing sound while breathing in, mucus production, chest tightness.Sometimes Anxiety can result in inability to take deep breaths but as you are not having other symptoms like sweating, fast heart rate and the fact that your symptoms are since 4 weeks, we can safely rule out anxiety as a probable causePneumonia can be another differential diagnosis, but we can safely rule that out as there is no fever or chest pain. Other causes like obesity, heart attack are also ruled out from your history. But to make a definite diagnosis I would still suggest a visit to a Pulmonary specialist. Hope you are satisfied with the answer. Thank you.
