Welcome to HCM
We understand your concerns
I went through your problem description carefully. I suggest you not to worry too much. You are just 23. For a healthy young person like you, it is not possible that the above mentioned problems arise. Are you living a healthy lifestyle? If not try to change it.
Heart burn is due to acidity and acidity is mostly due to junk food and improper food timings and of course lack of physical activity. Motion could be smooth if you drink enough water and eat balanced fiber rich food.
The pain around your chest is due to acid reflux
and it could not be related to heart. I suggest you to include garlic and ginger in your everyday meals.
Hope this clears your doubts. Available for further clarifications.
