Symptoms for angina other than chest pain include a sense of weight or pressure on the chest (often described as squeezing or fullness), shortness of breath, nausea, pain in the arms, neck, shoulders, back, or jaw (if it accompanies chest pain), fatigue, sweating, and dizziness. Unstable angina (angina that occurs for the first time, at unpredictable times, while at rest, is more severe than normal, or does not respond to angina medicine) is a medical emergency and might signal a heart attack - get to the emergency room immediately!
