Chest pain and fatigue can produce symptoms that mimic a heart attack, but in many cases, other conditions are the cause. Some of the most common causes of fatigue and chest pain are various forms of heart disease and pneumonia. In certain cases, fibromyalgia, which causes pervasive and expansive pain throughout the body, can also result in chest pain and fatigue.

When an individual complains of unexplained chest pain and fatigue, the patient's physician may suspect a disorder or condition involving the heart. One such condition called angina often produces symptoms like frequent bouts of chest discomfort and fatigue. This condition can produce a grasping feeling in the chest along with pressure. The pain can sometimes radiate to other areas, such as the arm or neck.

Many individuals suffering from angina often complain of extreme tiredness and fatigue along with chest pain. In one form of this condition, the symptoms of chest discomfort generally occur after physical exercise. A physician typically will suggest complete rest for the patient. Medication will sometimes be prescribed to control pain and discomfort.

There is a condition of the heart called mitral valve prolapse (MVP), and this can also produce chest pain and fatigue in some individuals. This condition affects the heart valve and can also lead to abnormal rhythms within the heart. A heart murmur can often be detected with a stethoscope. For some reason, this condition more commonly occurs in women than in men, and some experts believe it may be inherited. Medication or diet restrictions may be recommended by the physician.

Periacarditis can also cause chest pain and fatigue in many patients. This happens when tissues surrounding the heart become inflamed, typically from an infection. It is an acute condition, and if treated at the onset, it can often be cured with no permanent damage. If it is a mild case, it may not require any further treatment other than rest. Typically, the individual should be restored to good health in a short period of time. In rare cases, surgery may be required.

When a person develops pneumonia, common symptoms she may experience are chest pain and fatigue as well as a cough and fever. Pneumonia occurs when one or both lungs becomes inflamed and infected, either from a virus or bacteria. When fluids build in the lungs, this often leads to discomfort or extreme chest pain and fatigue. The course of treatment is typically bed rest and antibiotic therapy. In severe cases of respiratory distress, hospitalization may be required.

Other respiratory illnesses can cause chest pain and fatigue, and one condition that produces these symptoms is asthma. Asthma and chest pain are often related, so this typically makes it easy to diagnose when the patient is experiencing a flare-up. Patients who have bronchitis, either chronic or acute, will often have similar symptoms of discomfort in the chest. Bronchitis chest pain, along with a feeling of extreme fatigue, is common for many individuals to experience.
