For the past week, i have had shortness of breath, lightheadedness, headaches, discomfort in chest and between my shoulder blades and fatigue. this occurs even when I am just resting. I saw my GP last week for blood work and general check. she listened to my heart and breathing. it was fine.The blood work indicated an elevated liver enzyme, A1C was 6.5 and cholesterol ok. I am Type II diabetic.
