The discomfort may come and go. It may become worse with activity and improve with rest. Some people mistake it for indigestion, acid reflux, anxiety, or muscle strain.
Chest symptoms should be taken seriously, especially if they are new, unusual, or happen with sweating, nausea, breathlessness, weakness, or pain spreading to other parts of the body.
3. Shortness of Breath
Shortness of breath can appear before or during a heart attack. It may happen while climbing stairs, walking, doing simple chores, lying down, or even resting.
Some people notice they become winded much more easily than before. Others feel like they cannot take a deep breath. This can happen with chest discomfort, but it can also happen without obvious chest pain.
The original article explains that shortness of breath may occur because the heart is struggling to pump blood effectively.
4. Pain Spreading to the Arm, Back, Neck, Jaw, Shoulder, or Upper Abdomen
Heart-related discomfort does not always stay in the chest. It may spread to the left arm, both arms, the back, neck, jaw, shoulders, or upper stomach area.
