Hi Doctor, Only when I inhale deeply do I get a wheeze sound in my chest. It can be a high or low pitched sound sometimes can feel it as well. However, it does not happen all of the time I can go a couple of days with no sounds in my chest. Any idea what could be causing this. i also have Reflux and a small sliding hiatal hernia. One other symptom is pain across the upper portion of my back between the shoulder blades only upon moving my shoulders back or stretching my back. Your help in this matter is much appreciated.
