Why does rheumatic fever affect only heart throat and joints?

Rheumatic fever can affect more than just the heart, throat, and joints. It can also affect the skin, brain, and other organs. Here is a more complete list of the symptoms of rheumatic fever:

- Fever

- Fatigue

- Joint pain (most commonly in the knees, ankles, elbows, and wrists)

- Joint swelling

- Redness of the skin over the affected joints

- Pain in the chest

- Shortness of breath

- Heart murmur

- Fast heartbeat

- Hoarseness

- Difficulty swallowing

- Swollen lymph nodes

- Skin rash (erythema marginatum)

- Chorea (a movement disorder characterized by involuntary, jerky movements)

The reason why rheumatic fever affects these particular organs is not fully understood. It is thought that the bacteria that cause strep throat (Streptococcus pyogenes) produce toxins that can damage the tissues of the heart, joints, and other organs. These toxins can also cause the body to produce antibodies that attack its own tissues, leading to inflammation and damage.

Rheumatic fever is a serious condition that can lead to permanent damage to the heart and other organs. It is important to seek medical attention if you experience any of the symptoms of rheumatic fever.
