9. Fainting
Technically called syncope, more commonly known as “passing out” or “fainting,” this is usually related to the temporary, insufficient flow of blood to the brain. It most often occurs when the blood pressure is too low and can happen if you stand up too quickly—not cause for concern. However, if you pass out for no apparent reason, it could be because your heart is not pumping a normal supply of blood to the brain. This is cause for concern and means it’s time for a check up.
10. Throat, Jaw or Back Pain
It’s called “referred pain.” You feel pain in a part of your body that is not the actual source of the pain. In distress, the heart dials 911 on the nervous system hotline. When the message reaches the brain, the brain thinks it’s a pain message coming from somewhere other than the heart. Then the throat, jaw, arm, back or wherever feels the pain. If it lasts for more than a few minutes with no apparent cause, then that’s cause for you to call 911 or your doctor.
