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?
