Welcome to Health Care Magic
You MUST GO THE EMERGENCY DEPARTMENT – IMMEDIATELY.
Your description is highly suggestive.
It should be investigated as HEART PAIN – UNLESS PROVED OTHERWISE – especially with a strong family history.
In suspected heart attack
, TIME IS OF THE ESSENCE – if detected early, an attack may even be aborted / the amount of damage and complications can be reduced remarkably. The most important time is the first few hours.
Better be safe than sorry - treated if a problem is found / Happy, if it turns out otherwise
Go to ER / get yourself assessed / assured.
Wishing speedy recovery
