First off, happy birthday!!!
Second, age has nothing to do with heart attacks. Remember, there are children with cancer and diabetes
and all other types of diseases that usually older people get. Now is it unlikely that you are having true cardiac chest pain
, yes. But is it possible...yes. Alot of factors come into play especially with younger people and heart problems (family history, diet, exercise, risk factors, ect).
The chest pain you described is typical in angina
(which means cardiac pain) but it can be many other things. As a healthcare professional I must ADVISE YOU TO GO TO THE ER immediately and get it check out for you, your family and your baby to be. Better safe than sorry.
Remember every case is different so if you have additional concerns please ask your doctor.
