Welcome to HCM
After going through your history ,you are only 33 years of age and your symptoms and test which you hav egone through it very unlikely that you have significant heart disease
but still as you say you get pain which is subjective feeling.
But if it makes you uncomfortable you can always take a second opinion
from another cardiologist.
If you panic even a consultation with Psychiatrist
would be appropriate ant anti anxiety
or pain modulator medicine with mood elevator may solve your problem along with councelling.
If angina like pain persist a coronary angio/CT Angio may be done to see tate of coronary arteries.
Please do not worry at all ,
Please avoid stress and take up some yoga and meditation
