Endocarditis, an inflammation of the valves of the heart, causes symptoms that can be nonspecific and similar to those of many other conditions. For example, fever, malaise, weakness, and shortness of breath are common symptoms of endocarditis. Other symptoms that can occur with endocarditis are
- night sweats,
- joint and muscle aches, and
- swelling of the legs, abdomen, and feet due to fluid accumulation (edema).
Depending upon the cause of the endocarditis, other symptoms can occur. These include
- blood in the urine,
- pale skin, and
- painful red-purplish bumps under the skin of the fingers and toes known as Osler's nodes.
