Collarbone pain can make everyday life a lot tougher than you’d expect. Simple things—lifting your arm, carrying a bag, putting on a shirt, rolling over in bed, or even taking a deep breath—suddenly hurt. Sometimes it’s a sharp sting, other times it’s a dull ache, throbbing, soreness, or tenderness when you touch the area.
The collarbone, or clavicle if you want the medical name, runs across the top of your chest, connecting your breastbone to your shoulder blade. It helps steady your shoulder and shields nerves and blood vessels underneath. Lots of joints, muscles, and other stuff crowd around this bone, so collarbone pain isn’t always coming from the clavicle itself.
Most often, the causes are pretty everyday: an injury, joint irritation, muscle strain, lousy posture, or some trouble with your shoulder. Now and then, the culprit is something less common—like a pinched nerve, infection, swollen lymph node, or another medical problem.
Let’s dig into the main causes of collarbone pain, what different pain locations could mean, how to ease the discomfort, and when you really need to see a doctor.
Just a heads-up—this article isn’t a diagnosis. If your symptoms worry you, reach out to a healthcare professional.
When Is Collarbone Pain an Emergency?
Call for emergency help if your collarbone pain comes along with any of these:
– Chest pain, pressure, squeezing, or tightness
– Serious trouble breathing or severe shortness of breath
– Shooting pain spreading to the arm, jaw, neck, chest, or back
– Sweating, nausea, dizziness, or fainting
– Lips turning blue or gray
– Coughing up blood
– Your arm suddenly feels cold, blue, pale, numb, or swells up fast
– Sudden weakness in your arm or hand
– A bad fall, collision, or blow to the shoulder
– Bone sticking out or pressing against the skin
– Collarbone or shoulder suddenly looks crooked or out of place
If you’ve had an injury near your breastbone and then develop choking, hoarse voice, trouble swallowing, or breathing problems, go get help right away. In rare cases, the inner end of your collarbone can push backward and mess with important stuff in your upper chest. Never try to jam a bone that’s sticking out back into place.
See a doctor soon if you get a fever, warmth, redness, drainage, a hard or growing lump, unexplained weight loss, or pain that constantly wakes you up at night.
Where Can Collarbone Pain Happen?
The exact spot where you feel pain might give you clues, but it doesn’t guarantee a diagnosis.
Pain Near the Shoulder
Pain at the outer end of your collarbone often connects to the acromioclavicular (AC) joint. This spot tends to hurt more when you lift your arm, reach across your chest, carry something, or lay on that shoulder. AC joint sprains, arthritis, shoulder tendon problems, or injuries from weightlifting could be behind it.
Pain in the Middle of the Collarbone
Pain right in the middle could mean you’ve got a fracture, bone bruise, direct impact, or just overdid it. If the soreness sticks to one spot—especially after an accident—it’s worth getting checked out.
Pain Near the Breastbone
The inner end of the collarbone meets your breastbone at the sternoclavicular (SC) joint. If this area hurts, swells, clicks, or looks different on one side, you might have a sprain, arthritis, infection, inflammation, or maybe even a dislocation.
Pain Above or Under the Collarbone
Pain above or below the collarbone can come from neck or chest muscles, pinched nerves, shoulder issues, swollen lymph nodes, or chest-wall problems. If you notice tingling, weakness, arm swelling, color changes in your hand, a lump, or breathing troubles, make sure you get a proper checkup.
Common Causes of Collarbone Pain
1. Broken or Bruised Collarbone
Clavicle fractures usually happen after a hard fall onto the shoulder, a sports hit, car accident, or a solid blow. Pain hits you fast and gets worse when you try moving your shoulder.
Other signs:
– Swelling or bruising
– Intense tenderness
– Grinding or clicking sounds
– Visible bump
– Drooping shoulder
– Trouble lifting your arm
– Collarbone looks out of place
A bruised collarbone can feel similar but without a crack. Since both can hurt a lot, don’t assume severe pain after a big impact is “just bruising.” Docs often order an X-ray to be sure.
2. AC Joint Sprain or Shoulder Separation
The AC joint connects the end of your clavicle to the shoulder blade. Falling right onto your shoulder can stretch or tear the ligaments here—usually called a separated shoulder.
Sharp pain where your collarbone meets the shoulder is common. Reaching across your body or lifting your arm makes it worse. If it’s a major separation, you might see a bump pop up on top of your shoulder.
3. Muscle Strain and Bad Posture
Neck, chest, and shoulder muscles attach all around the clavicle. Lifting weights, working overhead, carrying heavy bags, coughing hard, or sleeping weird can leave them sore.
Sitting at a computer too long is a sneaky culprit. Rounded shoulders and a forward head pull extra on those muscles, and pain usually gets better if you move or fix your posture. But if numbness, swelling, weakness, or chest symptoms join in, get checked.
4. Shoulder Issues
Shoulder injuries often lead to collarbone pain. Possible causes include rotator cuff irritation, bursitis, arthritis, tendon strain, shoulder instability, or shoulder bone spurs
The pain gets worse when reaching overhead, fastening a seatbelt, putting on a coat, hauling groceries, or sleeping on that side. If you suddenly lose strength, movement, or have major pain after an injury, don’t wait.
5. Arthritis
Osteoarthritis can affect the AC joint near the shoulder or the SC joint by the breastbone. It creeps up slowly, causing dull aches, stiffness, tenderness, grinding, or pain when moving your shoulder.
Rheumatoid arthritis and other inflammation-based issues can hit these joints, too. If you notice pain in both collarbones, morning stiffness that won’t quit, swelling, heat, or pain in several joints, see your doctor.
6. Weightlifter’s Shoulder
Distal clavicle osteolysis (aka weightlifter’s shoulder) affects the shoulder end of the collarbone after too much bench pressing, dips, push-ups, or overhead work.
Usually hurts more when you lift or move your arm across your chest. Easing up helps, but training through sharp pain only worsens the problem.
7. Thoracic Outlet Syndrome
Here’s one you probably haven’t heard much about: nerves and blood vessels pass through a tight space between the clavicle and first rib. If that space gets squished, it can trigger pain in the collarbone, neck, shoulder, arm, or hand.
Watch for tingling, numbness, hand weakness, arm fatigue, swelling, cold fingers, or weird skin color changes. If any of that pops up, see a doctor—lots of things can cause these symptoms.
8. Pain Coming From the Neck or Chest
A pinched nerve or strained muscle in your neck can send pain toward your collarbone and arm. The pain may change when you move your head or lift your arm. Burning, tingling, numbness, or weakness may point to nerve irritation.
Some people try to relieve neck tightness by cracking their neck. However, forcefully cracking your neck may irritate the muscles, ligaments, joints, or nerves. Gentle movement is safer, especially if you already have neck and collarbone pain.
Upper-chest muscles can become sore after exercise, heavy lifting, coughing, or sneezing. But if your collarbone hurts when you breathe, the pain could also come from your lungs, heart, or another medical problem.
If breathing hurts and you also feel breathless, have chest pain, fever, faintness, a fast heartbeat, or cough up blood, seek emergency medical help immediately.
9. Infection or Swollen Lymph Node
Bone infection (osteomyelitis) isn’t common but is seriously painful. It causes deep pain, warmth, redness, swelling, fever, nausea, or drainage. It can happen after surgery, an open wound, or infection through the blood.
A bump near your collarbone might actually be a swollen lymph node instead. Most swell up from infection, but a hard, fixed, growing, or lingering lump—especially above the collarbone—should be checked right away.
10. Cancer
It’s rare for cancer to cause collarbone pain; most cases are just joint, muscle, or injury problems. But nighttime pain that won’t go away, a lump that’s getting bigger, unexplained weight loss, constant tiredness, or any history of cancer needs to be reviewed.
Collarbone Pain: Left vs. Right
Both sides can hurt for the same reasons—muscle strain, joint issues, shoulder problems, arthritis, bruising, fractures. Just because the pain is left-sided doesn’t mean it’s your heart, and right-sided pain isn’t always harmless. It’s the surrounding symptoms that matter most.
Pain with chest pressure, shortness of breath, sweating, nausea, faintness, or pain shooting into your jaw, arm, neck, or back—whether left or right—means you need emergency help.
Why Does My Collarbone Hurt Without an Injury?
Collarbone pain can slowly creep up even if you don’t remember an injury. Maybe you started a new workout, began lifting heavier stuff, sat longer at a computer, got a new backpack, had a coughing fit, or slept funny.
Look at the pattern:
– Pain with arm movement points to shoulder, AC joint, or muscle issues.
– Pain that changes when you move your neck might be the neck muscles or nerves.
– Super tender at one exact bony spot? Could be a bruise or stress injury.
– Tingling, burning, weakness, or numbness smells like nerve trouble.
– Warmth, swelling, redness, fever, or drainage—think infection.
– Pain with breathing or chest pressure needs urgent attention.
Collarbone Pain From Sleeping
Sleeping on your side can press on the AC joint and shoulder muscles. If your pillow’s too high or low, your neck might tilt and let your shoulder roll forward.
If mild soreness fades after you get up, it’s probably no big deal. Try sleeping on your back or a comfortable side for a few nights. Support your painful arm with a pillow, keep your neck neutral.
But see a doctor if pain keeps coming back, wakes you up, brings swelling or weakness, followed an injury, or doesn’t improve after switching positions.
How to Relieve Mild Collarbone Pain
If your pain is mild, you didn’t have a serious injury, and there are no warning signs, you can try some basic care at home.
1) Rest a bit
Lay off heavy lifting, pressing exercises, overhead work, or anything that triggers sharp pain. Gentle movement within your comfort range helps keep stiffness away, unless your doctor says you need a sling.
2) Cold or warmth
After a mild recent strain, use a cold pack (wrapped) for 15–20 minutes. If muscles are tight but not swollen, gentle warmth might feel better. Always protect your skin and stop if you feel worse.
3) Set up your workspace – and sleep
Raise your screen, support your elbows, keep your keyboard close, relax your shoulders, and get up regularly. Avoid direct pressure on the sore side during sleep—use pillows to prop your arm.
4) Pain meds
Acetaminophen (paracetamol) or anti-inflammatory medicines can help many adults, but they’re not safe for everyone.
Check with a pharmacist or doctor if you have liver, kidney, stomach, bleeding, or heart problems; take other medicines; or are pregnant. Always follow package directions.
Don’t deeply massage a suspected fracture, force a stretch through sharp pain, constantly crack the joint, wrap it tightly, or wear a sling for days without your doctor’s advice.
When Should You See a Doctor?
Book an appointment if your pain keeps getting worse, doesn’t stop, lasts more than a few days even with home care, messes up your sleep or work, or stops you from using your arm normally.
Also see a doctor if you have:
- Swelling or uneven collarbones
- A lump near or above the clavicle
- Numbness, tingling, or weakness
- Fever, warmth, or redness
- Recent surgery
- A weak immune system
- A history of cancer
How Is Clavicle Pain Diagnosed?
Your doctor will ask about injuries, exercise, work, sleep, fever, breathing issues, and pain in your neck, chest, shoulder, or back.
They’ll compare both collarbones, examine the acromioclavicular (AC) joints and sternoclavicular (SC) joints, test your neck and shoulder movements, check your strength and sensation, and assess circulation in your arms.
Which tests you get depends on what they suspect:
- X-rays spot most fractures and alignment problems
- Ultrasound checks for lumps or blood flow
- CT scan gives detailed bone images
- MRI looks at joints, muscles, tendons, nerves, and bone marrow
- Blood tests make sense if infection or inflammation seems likely
Frequently Asked Questions
Q. Is the clavicle the collarbone?
Yes—clavicle is just the medical term for collarbone.
Q. Is the collarbone part of the neck?
No, it’s at the bottom of your neck, but it’s part of the shoulder girdle. Neck muscles and nerves can still send pain toward it.
Q. Why does my shoulder and collarbone hurt?
The clavicle meets the shoulder at the AC joint, so irritation there can make both places ache. Other possibilities: muscle strain, bursitis, arthritis, rotator cuff problems, fracture, or neck pain spreading.
Q. Can stress cause collarbone pain?
Stress ramps up tension in neck, chest, and shoulder muscles and can make pain worse. But don’t blame stress if you have swelling, weakness, fever, chest pressure, breathing trouble, a lump, or lingering pain.
Q. Why does my collarbone click or pop?
Sometimes painless clicking is just normal joint or tendon motion. But if clicking comes with pain, swelling, weakness, instability, or a recent injury, get checked out.
Final Thoughts
Collarbone pain can start in the bone itself, joints, shoulder, muscles, neck, chest wall, nerves, or blood vessels. Mild soreness after sleep or activity often eases with quick fixes—rest, gentle movement, better support, and avoiding whatever caused it.
But if you’ve had a hard hit, see a visible change, have fever, swelling, weakness, weird color changes, chest pain, or breathing trouble—get medical care. If the cause stays mysterious or your collarbone just keeps hurting, an exam is way more useful than guessing based on pain location or type.
