I also have fatigue, dizzy spells, some chest pain, am a type 2 diabete, overweight, have degenerative osteoarthritis, fibromyalgia, and a smoker. My legs hurt
when I walk up stairs, and I get short of breath. My doctor is referring me to a cardiologist. Chest X-rays done yesterday show no abnormal gross findings. What am I looking at? Is this something that could be serious? I am 60 years old, a widow. My Dad died 3 years ago from a massive heart attack.
