I have a symptom that has mystified my cardiologist and I wonder if any of the readers have had a similar experience. When I start to have my usual symptoms and I'm outdoors, my eyes become very sensitive to glare and I have difficulty seeing. Any thoughts? FYI: I recently was traveling through the high country of Wyoming and Colorado where the elevation varied from 6000 to 9000 feet. My brother, who has had multyple bipasses, and my wife who has a mild case of emphe
syma (?), had difficulty with the conditions (low energy, difficulty breathing), but I didn't-????
