The pain of angina may make you sweat or make it hard to catch your breath. You may feel pain in your arm or neck as well as in your chest. If the pain is mild, it may go away after a minute or so of rest. If the pain is more severe, medicine may be needed. A medicine called nitroglycerin is used to treat severe angina.
Some people have angina that comes on with a certain level of activity and goes away easily.
They may have this kind of angina for a long time. This is called stable angina. When the pattern of angina changes a lot, it's called unstable angina. This is a sign of danger. Angina in someone who hasn't had it before, more episodes of angina with less exertion, and angina that comes on while you're resting are also danger signs.
