Thanks for your question on HCM.
I can understand your situation and problem.
In my opinion you are having mostly anxiety and related GERD (
gastroesophageal reflux disease ).
But since you have left sided
chest pain, better to get done ecg first to rule out cardiac cause.
If ecg is normal then no need to worry much for cardiac cause.
You are having anxiety and GERD.
Anxiety is well known risk factor for GERD.
So control of anxiety is needed.
Consult psychiatrist and get done
counselling sessions.
Try to identify stressor in your life and start working on its solution.
You may need anxiolytic drugs too.
So avoid stress and tension. Be relax and calm.
For GERD, start
Proton pump inhibitors. Avoid hot and spicy food.
Don't worry, you will be alright.
