I am experiencing shortness of breath with absolute minimal exertion. First noticed this a little over a month ago. Also, when I bend over at the waist (to pick something up off the ground as an example) I become very lightheaded. I am a 59 year old white male. No history (personal) of cardic problems. Also have been experiencing muscle cramps (feet/legs, chest/abd and arms/hands.
Thanks for your question on Chat Doctor. I can understand your situation and problem. By your history and description, possibility of lung disease (bronchitis) is more in your case. So better to get done PFT (Pulmonary Function Test) and chest x-ray to rule out bronchitis. If both are normal then get done ECG, 2d echo to rule out cardiac cause. So consult doctor and first diagnose yourself and then start appropriate treatment. You may need inhaled bronchodilators and inhaled corticosteroid (ICS). Hope I have solved your query. Wish you good health. Thanks.
