Can Strep Throat Cause Pain in the Chest?

Strep throat is a common bacterial infection primarily known for causing a sore throat. While chest pain is not a typical symptom, it can be associated with strep throat in specific circumstances, often indicating a complication. Recognizing these connections is important for knowing when to seek medical attention.

What is Strep Throat

Strep throat is an infection of the throat and tonsils caused by Streptococcus pyogenes (Group A Streptococcus or GAS). These highly contagious bacteria spread through airborne droplets or contaminated items. While common in children aged 5 to 15, it can affect anyone. Symptoms typically appear suddenly 2-5 days after exposure. These include a severe sore throat, fever, chills, swollen neck lymph nodes, and red, swollen tonsils, sometimes with white patches or pus. Petechiae (tiny red spots on the roof of the mouth) and scarlet fever rash can also occur.

How Strep Throat Can Lead to Chest Pain

While chest pain is not a direct symptom of strep throat, the infection can, in rare instances, lead to complications causing chest discomfort. One such complication is acute rheumatic fever, an inflammatory condition developing if strep throat is left untreated. This autoimmune response causes the immune system to mistakenly attack healthy tissues, including the heart.

This inflammation of the heart, called rheumatic carditis, can cause chest pain, shortness of breath, and fatigue. Rheumatic carditis can affect the heart muscle, the pericardium (lining around the heart), or heart valves, potentially leading to permanent damage. Valve damage can result in narrowing or leaking, impairing heart function.

Other less common complications can also cause chest pain. Strep throat might weaken the immune system, increasing susceptibility to secondary bacterial infections like pneumonia (lung infection) or pleurisy (inflammation of the lung lining), both of which can cause chest pain. These complications occur when strep bacteria spread to other body parts, leading to wider infection or inflammation.

Signs That Require Immediate Medical Care

Recognizing warning signs accompanying chest pain, especially in someone with or recovering from strep throat, is important for prompt medical intervention. Severe or worsening chest pain, particularly if crushing or radiating, requires immediate attention. This pain could signal cardiac involvement, such as rheumatic carditis or other inflammatory heart conditions.

Other important symptoms include shortness of breath, a rapid or irregular heartbeat, or fainting. These indicate the heart or lungs may be affected, requiring urgent medical assessment. New or unusual rashes, severe joint pain, swelling, and fatigue can also signal developing complications like rheumatic fever, which affects multiple body systems. If these symptoms appear, especially weeks after a strep throat infection, seek emergency medical care to prevent lasting damage.

The Importance of Treating Strep Throat

Prompt and complete treatment of strep throat is important to prevent complications, including those causing chest pain. Antibiotics are the primary effective treatment, eliminating Streptococcus pyogenes bacteria. Penicillin and amoxicillin are commonly prescribed, and completing the full 10-day course is important, even if symptoms improve earlier.

Antibiotic treatment speeds recovery, reduces symptom severity, and lowers the risk of spreading the infection. Crucially, it prevents complications like acute rheumatic fever, which can lead to permanent heart damage, including rheumatic heart disease. Early antibiotic treatment can reduce the risk of rheumatic fever by 70-80%.
