SymptomsBy Mayo Clinic Staff
Endocarditis may develop slowly or suddenly — depending on what's causing the infection and whether you have any underlying heart problems. Endocarditis signs and symptoms vary, but may include:
- Fever and chills
- A new or changed heart murmur — heart sounds made by blood rushing through your heart
- Aching joints and muscles
- Night sweats
- Shortness of breath
- Persistent cough
- Swelling in your feet, legs or abdomen
- Unexplained weight loss
- Blood in your urine (either visible or found in a doctor's viewing of your urine under a microscope)
- Tenderness in your spleen — an infection-fighting abdominal organ on your left side, just below your rib cage
- Osler's nodes — red, tender spots under the skin of your fingers
- Petechiae (puh-TEE-key-ee) — tiny purple or red spots on the skin, whites of your eyes or inside your mouth
When to see a doctor
If you develop signs or symptoms of endocarditis, see your doctor right away — especially if you have risk factors for this serious infection, such as a heart defect or a previous case of endocarditis.
Although less serious conditions can cause similar signs and symptoms, you won't know for sure until you're evaluated.
