Collarbone pain, also known as clavicle pain, can be a sharp, aching, or throbbing discomfort in the bone connecting your sternum (breastbone) to your shoulder blade. While often caused by a direct injury, understanding the various reasons for this pain is crucial for proper diagnosis and treatment. This article explores the common causes of clavicle pain, associated symptoms, and treatment options.

Common Causes of Clavicle Pain
Several factors can contribute to clavicle pain, ranging from acute injuries to underlying medical conditions.
Fractures and Breaks
Collarbone fractures are prevalent, often resulting from falls or direct impact to the shoulder. Symptoms include intense pain, swelling, and limited arm movement. Treatment typically involves immobilization with a sling or brace, pain medication, and in severe cases, surgery.
Acromioclavicular (AC) Joint Separation
The AC joint connects the clavicle to the shoulder blade. Separation occurs when ligaments supporting this joint are injured, often due to a fall or direct blow. Symptoms include pain, tenderness, swelling, and bruising around the joint. Treatment ranges from immobilization for minor injuries to surgery for severe separations.
Distal Clavicle Osteolysis
This overuse injury affects the end of the clavicle near the shoulder, commonly seen in weightlifters and athletes performing repetitive overhead movements. Pain during and after activity, tenderness, and swelling are characteristic symptoms. Treatment involves rest, ice, NSAIDs, activity modification, and sometimes cortisone injections.
Arthritis
Osteoarthritis, a degenerative joint disease, can affect the sternoclavicular (SC) joint where the clavicle meets the breastbone. Cartilage breakdown leads to pain and stiffness. Treatment focuses on pain management with over-the-counter medications like acetaminophen and cortisone injections.
Thoracic Outlet Syndrome (TOS)
TOS encompasses conditions where nerves or blood vessels in the space between the clavicle and first rib are compressed. Causes include traumatic injuries, repetitive arm movements, congenital abnormalities, obesity, or overdeveloped muscles. Symptoms vary depending on the specific type of TOS, ranging from pain and weakness in the arm and shoulder to swelling, discoloration, and tingling in the hand and fingers. Treatment includes physical therapy, NSAIDs, and in some cases, surgery.
Cancer
Rarely, clavicle pain can be a symptom of cancer. Diagnosis and treatment depend on the specific type and stage of cancer.
Osteomyelitis
Osteomyelitis is a bone infection that can affect the clavicle. Causes include bacterial or fungal entry through a wound, a compound fracture, or bloodstream infection (sepsis). Symptoms include pain, warmth, and swelling around the affected area. Treatment typically involves intravenous antibiotics and sometimes surgery to remove infected tissue.
Condensing Osteitis
This rare, benign condition causes pain and swelling at the end of the clavicle near the breastbone. The cause is unknown, and treatment often involves antibiotics.
At-Home Care for Clavicle Pain
For pain caused by minor trauma or muscle strain, initial at-home treatment can provide relief. Immobilize the arm with a sling, apply ice for 20 minutes at a time (with a towel between the ice and skin), and rest the affected area.
When to Seek Medical Attention
While not all clavicle pain is serious, consult a healthcare provider if the pain is sudden, severe, or chronic. Seek immediate medical care if you experience a major clavicle injury accompanied by confusion, shortness of breath, chest pain, fainting, or pain radiating to the arms, shoulders, neck, or back. A deformity or bump at the site of injury also warrants immediate attention. While clavicle pain isn’t directly linked to heart issues, referred pain from a heart attack can sometimes be felt in the collarbone area.

Summary
Clavicle pain can stem from a wide range of causes, from injuries to infections and underlying medical conditions. Treatment depends on the underlying cause and can range from conservative measures like immobilization and pain medication to surgery in more severe cases. It’s essential to consult with a healthcare professional for accurate diagnosis and appropriate treatment to address your specific situation.
