I work out regularly. I am having difficulty breathing with pain in the middle of my chest that is also between my shoulder blades.  I get a headache and slightly nauseated when this happens.  This usually startes happening only 10 - 15 minutes into exercising.  Whats wrong?
Thanks for your question on Chat Doctor. I can understand your concern. Since your all symptoms are started after 10-15 minutes of exercise (exertion), possibility of cardiac disease is more. So consult cardiologist and get done blood pressure monitoring, ECG, 2d echo and stress test (trade mill test). You may need cardiac supportive Chat Doctor.  Don't worry, you will be alright. Avoid stress and tension, be relaxed and calm. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
