Hi, I am a healthy 22 year old male. I exercise daily and watch what I eat. For more than a year now I've been getting shortness of breath, which comes with tightness in my eyes and minor dizziness. I've been to the cardiologist, pulmonary doctor, gastrointestinal doctor, ENT, endocrinologist, and allergist; every doctor did every test possible and nothing has been found. I'm aware it can be anxiety but I don't feel anxious or stressed at all, something has to be wrong.
