Hello and hope you are doing well.
Inadequate oxygenation can produce symptoms of breathlessness, as the body tries in an effort to compensate for the decreased oxygen supply. The breathlessness could be due to cardiac or lung disorders. Breathlessness on exertion could be due to the decreased lung function. Again in cardiac disorders the heart is unable to pump the blood adequately, more so when subjected to stress like exercise. The chest pain could also be due to decreased oxygenation. Certain systemic disorders like anemia, diabetes, vitamin deficiencies and thyroid disorders can cause these symptoms. So please consult your primary care physician who may ask for an EKG or a treadmill test to rule out a cardiac cause for the pain. He may even ask for blood tests and an X ray chest. Lung function tests could further help in evaluation.
Hope this helped and do keep us posted.
Yes, schedule an appointment with your doctor. It could be cardiac in nature or something completely unrelated, but it does need to be checked out.

You haven’t say how old are you, but regardless I would go to the doctor as soon as I can.
