Sternum Pain: Causes and Connections to Arthritis - Orthopedics

More Info

---

Sternum pain can be a concerning symptom, especially for someone with a history of rheumatoid arthritis (RA). The sternum, or breastbone, is located in the center of the chest and connects to the ribs via cartilage. Pain in this area can arise from various causes, and understanding these can help in managing your symptoms effectively.

Given your background of rheumatoid arthritis, it is essential to consider how this autoimmune condition might contribute to your sternum pain. RA can lead to inflammation in various joints and tissues throughout the body, including the costosternal joints, which connect the ribs to the sternum. This inflammation can result in pain, tenderness, and discomfort in the chest area, particularly during movements such as turning in bed or when pressure is applied.

In addition to RA, other potential causes of sternum pain include:
1. Costochondritis: This is an inflammation of the cartilage that connects a rib to the sternum. It can cause sharp pain in the chest, which may worsen with movement or pressure. Costochondritis is often benign and can be treated with anti-inflammatory medications.

2. Muscle Strain: If you have been sleeping in a position that puts strain on your chest muscles or if you have engaged in activities that require heavy lifting or twisting, you might experience muscle strain, leading to pain in the sternum area.

3. Injury: Trauma to the chest, whether from a fall, accident, or even vigorous coughing, can cause pain in the sternum. If you have had any recent injuries, this could be a contributing factor.

4. Gastroesophageal Reflux Disease (GERD): Sometimes, pain in the chest can be mistaken for sternum pain when it is actually related to acid reflux. GERD can cause a burning sensation in the chest, which may mimic sternum pain.

5. Cardiac Issues: While less likely given your description, it is crucial to rule out any cardiac-related issues, especially if the pain is accompanied by other symptoms such as shortness of breath, sweating, or radiating pain to the arms or jaw.

Given your existing condition of rheumatoid arthritis, it is advisable to consult with your healthcare provider for a thorough evaluation. They may recommend imaging studies, such as X-rays or MRIs, to assess the sternum and surrounding structures for any signs of inflammation or damage. Blood tests may also be necessary to evaluate the level of inflammation in your body.

In the meantime, managing your pain with over-the-counter anti-inflammatory medications, such as ibuprofen or naproxen, may provide some relief. Applying heat or cold packs to the affected area can also help alleviate discomfort. However, it is crucial to avoid self-diagnosing and to seek professional medical advice to ensure that your symptoms are appropriately addressed.

In summary, while your rheumatoid arthritis could be a contributing factor to your sternum pain, it is essential to consider other potential causes. A comprehensive evaluation by your healthcare provider will help determine the underlying issue and guide you toward the most effective treatment options.
