What are the symptoms of sternoclavicular joint inflammation?
Generally, sternoclavicular arthritis is a type of osteoarthritis and may be caused by degenerative bone changes. Symptoms include voice abnormalities, redness and swelling in the sternum area, muscle spasms, sternal pain, and restricted movement. If discomfort occurs, it is advisable to seek medical attention promptly. A detailed analysis is as follows:
1. Voice Abnormalities
Inflammation of the sternoclavicular joint can damage the cartilage tissue within the joint. Cartilage primarily functions to reduce friction and impact during joint movement. When cartilage is damaged, the smoothness of the joint surface decreases, causing friction during movement. This friction may produce abnormal sounds, similar to joint crepitus.
2. Redness and Swelling in the Sternum Area
Sternoclavicular joint inflammation triggers an inflammatory response in surrounding tissues. Inflammation is the body's natural reaction to injury or infection, aimed at eliminating pathogens and repairing damaged tissue. During inflammation, increased blood flow leads to local congestion and swelling, resulting in redness and swelling in the chest area.
3. Muscle Spasms
Inflammation caused by sternoclavicular arthritis stimulates surrounding muscles, leading to muscle contraction and spasms. The inflammation causes local tissue congestion and swelling, which irritates nerve endings and thereby induces muscle spasms.
4. Sternal Pain
Inflammation of the sternoclavicular joint may lead to joint instability, meaning the structure and function of the joint are compromised, preventing normal alignment and motion. This instability may cause excessive tension in the muscles and ligaments around the joint, resulting in pain in the sternum area.
5. Restricted Movement
Sternoclavicular joint inflammation causes pain and discomfort in the sternal region, with pain often worsening during physical activity—especially during vigorous exercise, lifting heavy objects, or deep breathing. To avoid pain, patients may consciously reduce or avoid certain activities, leading to limited mobility.
In daily life, it is recommended to choose low-impact exercises suitable for individual conditions, such as walking, swimming, or cycling. These activities can strengthen muscles and improve joint stability.
