Chest pain: Extreme discomfort that feels like squeezing, pressure or tightness. May be accompanied by pain radiating down an arm, nausea, vomiting, sweating or difficulty breathing.
What it might mean: A heart attack. Other possibilities include gastrointestinal reflux or GER (sometimes called acid reflux), which happens when stomach contents flow back up into the esophagus.
GER isn’t life-threatening, but it can become a chronic condition.
