Right-sided chest pain?


Hello doctor, I have recently experienced slight pain in the middle of my chest when lying on my right side, which feels like tenderness inside (the pain subsides when I lie on my right side).
Due to my work, I often have pain around my right clavicle, but I have never felt this way before, especially with the chest pain when lying on my right side these past few days.
Could you please tell me what this condition might be? Thank you, doctor.

Hello: There are many possible causes of chest pain, including muscle inflammation, fasciitis, costochondritis, mediastinitis, pleuritis, lung inflammation, and cardiac issues.
It is not possible to deduce the cause based solely on symptoms.
Please visit a thoracic specialist for further evaluation.

More Info


Right-sided chest pain when lying down can be concerning, and it's important to consider various potential causes. Based on your description, the pain seems to be localized in the center of the chest and is exacerbated when lying on your right side. This could suggest several possibilities, which can range from musculoskeletal issues to more serious conditions.

1. Musculoskeletal Pain: One of the most common causes of chest pain, especially in younger individuals, is musculoskeletal pain. This can occur due to muscle strain, inflammation of the costal cartilage (costochondritis), or irritation of the muscles around the chest wall. Given that you mentioned experiencing pain around the right clavicle due to work, it’s possible that repetitive strain or poor posture could be contributing to your symptoms. When lying on your side, the pressure on these inflamed or strained muscles could lead to increased pain.

2. Nerve Compression or Irritation: Another possibility is nerve compression or irritation, particularly if you have a history of neck or upper back issues. Conditions such as a herniated disc in the cervical spine can lead to referred pain in the chest area. If certain positions exacerbate the pain, it could indicate that the nerves are being compressed or irritated in those positions.

3. Referred Pain from Internal Organs: While less common, it’s important to consider that pain in the chest can sometimes be referred from other organs. For example, issues with the lungs (like pleuritis or pneumonia), the heart (though less likely given your age and description), or even gastrointestinal issues (like acid reflux or esophageal spasms) can present as chest pain. However, these typically have additional symptoms, such as shortness of breath, cough, or gastrointestinal discomfort.

4. Anxiety and Stress: Sometimes, anxiety can manifest as chest pain, particularly if you are under stress or experiencing anxiety about your health. This type of pain is often described as sharp or tight and can be exacerbated by certain positions or movements.

5. Costochondritis: This is an inflammation of the cartilage that connects a rib to the sternum. It can cause localized pain that may worsen with certain movements or positions, including lying down.

Given that your symptoms have changed recently and are causing you concern, it is advisable to seek medical attention. A healthcare provider can perform a thorough evaluation, which may include a physical examination and possibly imaging studies (like an X-ray or MRI) to rule out any serious underlying conditions. They may also assess your posture and ergonomics, especially if your work involves repetitive motions or prolonged sitting.

In the meantime, you might find relief by adjusting your sleeping position, using supportive pillows, or applying heat to the affected area. Over-the-counter anti-inflammatory medications may also help alleviate pain, but it’s best to consult with a healthcare professional before starting any new medication.

In summary, while musculoskeletal issues are a likely cause of your right-sided chest pain when lying down, it’s essential to have a comprehensive evaluation to rule out other potential causes. Your health and peace of mind are paramount, so don’t hesitate to reach out to a healthcare provider for further assessment.
