Warning signs of a heart attack:

It can feel like uncomfortable pressure, squeezing, fullness or pain.Discomfort in other areas of the upper body. Symptoms can include pain or discomfort in one or both arms, the back, neck, jaw or stomach.Shortness of breath with or without chest discomfort.Other signs may include breaking out in a cold sweat, nausea or lightheadedness.Call and check in with your Dr. or if you feel you are having a heart attack seek emergency care.
Do I think you are having a problem with your heart - it is not up to me to think yes or no but to advice you to call or present yourself.
If it turns out to be anxiety - no foul...................
I do care about your health.
