Shoulder dislocation: symptoms, treatment, and when to worry
Last updated September 3, 2026.
A dislocated shoulder means the ball at the top of your upper arm bone has come out of the shoulder socket. It usually follows a fall, a collision in sport, or a forceful twist of the arm. It is intensely painful, the shoulder often looks visibly out of shape, and you will not be able to move the arm normally.
What should you do right away?
Get medical help as soon as possible and do not try to push the joint back in yourself, as that can damage nerves, blood vessels, and torn tissue. While you wait, support the arm in a sling or with a towel, hold an ice pack wrapped in a cloth against the shoulder for up to 20 minutes at a time, and take simple pain relief following the packet directions. Keep the upper arm still, and do not drive yourself to the emergency department.
What actually helps?
- Get it put back properly: at the hospital, an X-ray confirms the dislocation, then a doctor guides the joint back into place with pain relief or sedation. Most people feel near-instant relief once it is back in.
- Wear the sling: the arm is supported in a sling for the first few weeks while the torn tissues settle.
- Do the physio: guided exercises rebuild strength and stability and are the main defense against stiffness and repeat dislocations.
- Respect the timeline: recovery usually takes up to 12 weeks, and up to 16 weeks before a full return to contact or overhead sports.
- Ask about surgery after a first dislocation: once a shoulder has dislocated, the risk of it happening again rises, especially in younger, active people. A scan and sometimes surgery are considered to lower that risk.
When is it an emergency?
A dislocated shoulder is itself an emergency. Go to an emergency department now if, after an injury, you cannot move your arm, the shoulder looks out of place or a different shape, or it is severely painful, bruised, or swollen. Call 911 if you cannot get there safely yourself, and get urgent help for any numbness, tingling, coldness, or color change in the arm or hand, which can mean nerve or blood vessel damage.

Common questions
Can you pop a dislocated shoulder back in yourself?
No. Movies make it look simple, but forcing the joint back without training can tear ligaments further, trap tissue, or damage the nerves and blood vessels that run past the shoulder. The reduction is done in hospital with pain relief or sedation and an X-ray to confirm position. At home, your job is a sling, ice, and getting to care, not heroics.
How long does a dislocated shoulder take to heal?
Most people recover within about 12 weeks. The sling comes off after the first few weeks, then physiotherapy rebuilds movement and strength. Return to contact sports or heavy overhead activity usually takes up to 16 weeks or longer, and going back too early is one of the easiest ways to dislocate it again.
Why does my shoulder keep dislocating?
A first dislocation stretches or tears the labrum and ligaments that hold the joint stable, and once those are damaged the ball can slip out more easily. The younger you are at the first dislocation, the higher the chance it recurs, and repeat dislocations are common in contact and overhead sports. Surgery to repair or tighten the stabilizing tissue is often discussed after repeat episodes.
Do I need surgery for a dislocated shoulder?
Not always. Many first-time dislocations are managed with a sling and physiotherapy alone. Surgery becomes part of the conversation when the shoulder keeps dislocating, when scans show significant structural damage, or when a young, active person has a high recurrence risk. The decision weighs your age, sport, and what the imaging shows.
When can I drive after a dislocated shoulder?
Only when you can control the wheel fully and perform an emergency maneuver without pain, which realistically means after the sling is off and strength is returning. Driving in a sling is unsafe and may affect insurance. Your doctor or physiotherapist should confirm readiness before you get back behind the wheel.
What is the difference between a dislocation and a separated shoulder?
They are different joints. A dislocation means the ball of the upper arm bone has left the main shoulder socket. A separated shoulder, or AC joint injury, is where the collarbone meets the shoulder blade at the top of the shoulder, and it causes a visible bump there rather than the arm hanging out of place. Both need assessment, but treatment and recovery differ.
