These signs may indicate a condition known as angina which occurs when the heart muscle does not receive enough oxygen. This results in discomfort or pressure around the chest; it may also radiate down the arm, up into the neck or back. If these are the symptoms you’re experiencing, then it’s important to get medical help right away because angina could mean that there is something wrong with your heart. Treatment options for angina include medicines, and lifestyle changes such as quitting smoking, eating a healthy diet, and getting regular exercise; sometimes surgery or other procedures might be necessary too if they can help improve blood flow to the heart.
