For the past 3 weeks I've been belching with chest and upper back discomfort. Specifically, in the mornings I'm OK but throughout the day I feel shortness of breath
area. Interestingly, I also feel the symptoms when I'm relax. I went to the doctor and my chest x-rays, blood work are negative but the doctor reported he heard "wheezing" sounds and prescribed an inhaler. I've been taking over the counter prilosec for about two weeks and using an inhaler but I'm still feeling the same way.
Unfortunately, my doctor can't figure out my symptoms, what kind of specialist is recommended?
