question: I am a 73 yr old diabetic (53 yrs diabetic, last A1C 7.4) in good condition (was walking 3 to 4 dogs about 2 miles twice a day but cannot now) prior to this problem and have had difficulty breathing for about a month. This came on suddenly (overnight) after a long day working in the sun. Due to a shortage of doctors (Butte, MT) I have not yet been able to see a pulmonologist (sp?). The problem is intermittent with some days being near normal and other days totally debilitating. Heart and MRI are normal. I recently move from sea level to 5500 ft but had 30+ days to acclimate before this happened. Any suggestions?
