Sternoclavicular joint pain: symptoms, causes & relief

If you ever felt a sudden, sharp ache right where your collarbone meets the center of your chest, you're probably dealing with sternoclavicular (SC) joint pain. It can pop up after a tumble, from arthritis, or even from everyday wearandtear.

Below you'll get the quick answers you needwhat's causing it, when to see a doctor, and how to ease the painso you can stop guessing and start feeling better.

Understanding SC joint pain

What the SC joint actually is

The sternoclavicular joint is the tiny, but mighty, connection between your clavicle (the "collarbone") and the sternum (the breastbone). It's the only place the arm literally attaches to the trunk of your body, which is why a problem there can feel like it's radiating all over your shoulder and neck.

Quick anatomy snapshot

• Articular cartilage covers the ends of the clavicle and sternum, allowing smooth movement.
• Four strong ligaments hold the joint in place, protecting the nearby vessels and windpipe.
• The joint's range of motion is limitedmostly a bit of upanddown and forwardbackward motionbut that's enough for everyday activities.

For a clear diagram, check the AAOS guidelines on SC joint anatomy.

Common causes of SC pain

Cause	Typical age / risk	Key trigger	How pain feels
Trauma / dislocation	Any age, especially athletes	Direct blow, fall, car crash	Sharp, worsens with arm movement
Arthritis (OA/RA)	50+ for OA, any age for RA	Wearandtear or autoimmune inflammation	Dull ache, stiffness, possible swelling
Infection (septic arthritis)	Immunocompromised, recent surgery	Bacterial spread from nearby infection	Rapid swelling, fever, severe pain
Overuse / repetitive strain	Athletes, manual laborers	Repeated lifting or pushing	Gradual aching, worsens after activity

Trauma and dislocation

A hard impact can push the clavicle out of its socket. Anterior dislocations are usually painless enough to be treated with a sling, but a posterior dislocation is a medical emergencytiny structures like the trachea and major blood vessels sit right behind the joint.

Arthritic degeneration

Osteoarthritis slowly chips away the cartilage, while rheumatoid arthritis attacks the joint's lining. Both can turn the SC joint into a source of chronic "clavicle joint pain."

Infection and rare disorders

Though uncommon, a bacterial infection can invade the joint space, leading to septic arthritis. Fever, redness, and a rapidly expanding swelling are redflag signs that demand immediate care.

Recognizing SC pain symptoms

Typical signs

• Localized pain directly over the joint.
• Swelling or a tender lump.
• Crepitus (a grinding sensation) when moving the shoulder.
• Limited range of motion, especially when reaching across the chest.

Redflag symptoms

If you notice any of the following, don't wait:

• Difficulty breathing or a choking feeling.
• Visible deformity of the joint.
• Fever, chills, or rapid swelling.

Selfassessment checklist

Answer "yes" or "no" to each:

1. Is the pain sharp when I lift my arm?
2. Does the area feel warm or swollen?
3. Do I have any fever or night sweats?
4. Can I see a bump or misalignment?

When to see a professional

Redflag timeline

If pain lasts more than two weeks, worsens, or is accompanied by fever or breathing difficulty, schedule an appointment right away. Early evaluation can prevent a simple strain from turning into a complex joint problem.

What the doctor will do

A typical visit includes a thorough history, palpation of the joint, rangeofmotion testing, and a neurovascular check to ensure nothing is pressing on nearby vessels or nerves.

Ask the doctor

• "Is my SC joint stable after this injury?"
• "Do I need an Xray, CT, or MRI?"
• "What are the nonsurgical options for relief?"

Diagnosis and imaging

Physicalexam steps

Clinicians will press around the joint, ask you to move your arm in different directions, and listen for any "click" or pain spikes. They'll also check your pulse and sensation in the armcritical because the SC joint sits near major blood vessels.

Imaging options

• Xray: Firstline; shows fractures or dislocations.
• CT scan: Offers a 3D view, essential for spotting posterior dislocations.
• MRI: Best for softtissue damage, ligament tears, or early arthritis.

Sample radiology report

"CT of the sternoclavicular region demonstrates an anterior dislocation of the left clavicle with mild surrounding edema. No vascular compromise observed."

Treatment options

Nonsurgical first line

• Rest and activity modificationavoid overhead lifts and heavy pushing.
• Ice the area for 1520 minutes, 34 times a day.
• NSAIDs such as ibuprofen or naproxen for pain and inflammation.
• Corticosteroid injection if inflammation persists after a few weeks.
• Physicaltherapy program focusing on gentle rangeofmotion, followed by scapular stabilizer strengthening.

Surgical options (when conservative care fails)

Procedure	When indicated	Key benefit / risk
Closed reduction	Acute dislocation, especially posterior	Quick realignment; may need sedation
Open reduction & ligament reconstruction	Unstable or recurrent dislocation	Restores stability; surgical risks apply
Joint resection / medial clavicle excision	Endstage arthritis	Pain relief; potential neurovascular injury
Total SCjoint arthroplasty	Severe arthritis unresponsive to other measures	Restores motion; limited longterm data

Decisionmaking flowchart

Start with "pain try conservative reassess after 6 weeks if still severe, consider imaging discuss surgical options."

Rehab & recovery timeline

Phase1 (02 weeks)

Immobilize with a figureeight brace or sling. Perform pendulum swings and gentle neck stretches to keep circulation moving.

Phase2 (26 weeks)

Begin activeassisted rangeofmotion exerciseswall slides, scapular retractions, and isometric shoulder shrugs.

Phase3 (612 weeks)

Progress to resistance band work, light dumbbell rows, and functional drills like reaching across the body or gentle pushups.

Sample PT protocol

Week	Exercise	Sets / Reps	Progression cue
12	Pendulum swings	230sec	Maintain pain <3/10
34	Wall slides	310	Full arm reach without pain
56	Scapular rows (band)	312	Control movement, avoid shrugging
712	Light dumbbell press	38	Increase weight only if pain stays low

Prevention & selfcare

• Warmup thoroughly before contact sportsdynamic shoulder circles, band pullaparts.
• Wear protective shoulder pads if you play rugby, football, or do highimpact work.
• Strengthen the scapular stabilizers (rows, YTW exercises) at least twice a week.
• Schedule periodic checkups if you already have sternoclavicular arthritis or a prior injury.

Realworld perspectives

Patient story

Jake, a 28yearold rugby player, felt an excruciating pop in his left chest after a tackle. Within hours the area swelled, and his breathing felt "tight." At the ER, a CT scan confirmed a posterior SC joint dislocation. He underwent a closed reduction under sedation, followed by six weeks of immobilization and a structured PT plan. Today, Jake is back on the field, but he now always does a proper pregame shoulder warmup and carries a compression wrap for extra support.

Expert commentary

Dr. Maya Patel, orthopedic shoulder specialist at the Cleveland Clinic, notes, "Posterior dislocations are rare but dangerous because of the structures behind the joint. Prompt imagingpreferably a CTcan be lifesaving. For most SC joint pain, conservative treatment works; surgery is truly a last resort."

Conclusion

Whether it's a sudden injury, creeping arthritis, or just everyday wear, sternoclavicular joint pain can be frustratingbut it's often manageable. Most cases improve with rest, antiinflammatories, and a guided rehab program. However, redflag signs like breathing trouble or rapid swelling demand immediate medical attention, and persistent instability may call for surgical intervention.

Listen to your body, get a professional evaluation when needed, and follow a personalized recovery plan. If you're battling SC joint pain, consider reaching out to an orthopedic specialist todayyour shoulder (and your peace of mind) will thank you.
