I am 72, have some shortness of breath while sitting, sometimes dry cough (like from taking a new BP drug), and back discomfort and pain between my shoulder blades when breathing. I had the same back pain a good 15-20 years ago, but xrays etc showed nothing and Dr. figured it was heart burn. Haven t had a lot of it since until a week or so ago. I have been moving over the last week so also have had a lot of sweating and cold sweats and tiredness. I also have diabetes type 2 and take medication (Metformin 1000mg 2x day and Lantus about 27 units at bedtime) for it. My last A1C (almost 3 months ago) was 8. I take other medications for high BP, high Cholesterol, depression, Osteopenia, and Hypothyroidism. Sometimes the upper back discomfort subsides a little. I have not taken my temperature. Have had several chills over the last week too.
