Three docs have only come up with possible allergies. Allergy meds don't work. My husband has severe COPD, Alzheimers and possibly acid reflux. This gurgling started about a month ago. Since then, he has also been diagnosed with pneumonia. The pneumonia seems to be getting better, but the gurgling in his sleep continues. Three doctors ( primary care, pulmonologist, and allergist) have come up only with possible allergies. But, the allergy meds do not help. Now they say try added acid reflux meds to see if that works. Anyone else experienced this.?
