I am 50 years old, non-smoker (quit 24 years ago), active, history of heart disease in my family (dad), 187 pounds, 5 11 but I continue to have an uncomfortable sensation in my throat that feels like I am inhaling smoke creating a cough. No heaviness or tightness in my chest but I do get some discomfort in my left shoulder and arm from time to time. I also have some tingling in my feet. Does any of this sound like heart disease, lung disease, circulation problems.?
