Shoulder Dislocation: Symptoms, Care and Recovery

01Dislocation

What a shoulder dislocation is

The shoulder is a ball-and-socket joint: the rounded top of the upper arm bone sits in a shallow, cup-shaped socket that is part of the shoulder blade. Mayo Clinic explains that the shoulder is the body’s most flexible joint, which makes it the joint that dislocates most often.

It can dislocate forward, backward or downward. Most dislocations are forward, also called anterior. When the joint comes out of place, the ligaments that connect the bones may stretch or tear, which can make the injury more serious. It takes a strong force, such as a sudden blow or extreme twisting of the shoulder, to pull the bones apart.

02Related injuries

Dislocation versus subluxation and other shoulder injuries

Mayo Clinic notes that a dislocation can be complete or partial. In a partial dislocation, often called a subluxation, the upper arm bone is partly in and partly out of the socket; our guide on shoulder subluxation covers that situation.

A shoulder injury can also affect other structures. Injuries to the joint at the top of the shoulder, where the collarbone meets the shoulder blade, are a different problem from a dislocation of the main shoulder joint, although both can follow a fall. A dislocation can also tear the muscles, ligaments, tendons or the rim of cartilage around the socket; see our guide on a shoulder labral tear. Telling these injuries apart requires examination and usually an X-ray.

03Symptoms

Symptoms after a fall or blow

Mayo Clinic and the NHS describe these symptoms after a shoulder injury:

• a shoulder that looks out of place or has changed shape
• intense pain
• swelling or bruising around the shoulder
• being unable or barely able to move the arm or shoulder
• numbness, weakness or tingling in the neck, shoulder or arm
• muscle spasms around the shoulder, which can make the pain worse

Common causes are contact sports and sports with falls, such as skiing, gymnastics or volleyball; hard blows such as in traffic accidents; and awkward falls, for example from a ladder or after tripping. Mayo Clinic notes that dislocations are most common in people in their teens and twenties, particularly athletes in contact sports, but anyone can dislocate a shoulder.

05Before treatment

What to do before professional care

While you wait for treatment, the NHS and Mayo Clinic advise:

• not moving the upper arm, and not trying to pop the shoulder back in yourself
• supporting the arm in the position it is in, with a sling, a towel or your other arm
• gently holding an ice pack or ice wrapped in a cloth to the shoulder, which the NHS suggests for up to 20 minutes every 2 to 3 hours, to help with pain and swelling
• using a simple painkiller from a pharmacy if needed, always following the instructions on the packet

Mayo Clinic warns that trying to fix the shoulder yourself can damage nerves, blood vessels or soft tissue around the joint. Pulling, twisting or asking someone untrained to put it back are not safe alternatives to hospital care.

06Hospital treatment

Examination, X-ray and putting the shoulder back

According to the NHS, you will usually have an X-ray to confirm the dislocation. If it is dislocated, a doctor rotates the arm back into place, a procedure called reduction, after giving a local anesthetic or a sedative so that you do not feel pain.

Once the arm is back in place, you are given a sling to support it. The NHS notes that you may later be offered a scan to check whether the shoulder has been damaged; further imaging is decided according to the injury, not done routinely for everyone.

07Rehabilitation

Sling, physiotherapy and recovery

The NHS explains that you will need to wear the sling for the first few weeks and that a physiotherapist may recommend regular shoulder exercises to help reduce pain and stiffness. The hospital may also recommend regular physiotherapy to make the shoulder muscles stronger and reduce the risk of another dislocation. Mayo Clinic advises continuing the strength and stability exercises prescribed for the injury.

Exercises start when, and in the way, the treating team indicates, after the shoulder has been put back and assessed. The type of exercise, how far the arm can move and how quickly to progress depend on the injury and any damage found, which is why a generic routine found online is not a substitute.

For adults who have been treated and cleared to start rehabilitation, our physiotherapy practice in Bilbao offers a program adapted to the injury and to the instructions of the treating team (consultations are in Spanish). A suspected dislocation needs emergency care first.

08Recurrence

Recurrence, surgery and return to activity

Once a shoulder has dislocated, it is more likely to happen again. The NHS says the risk depends on your age and how well the joint healed, and Mayo Clinic notes that it is higher after a severe injury. Following the hospital’s advice and keeping up the prescribed exercises help reduce it.

Not every dislocation needs surgery. The NHS notes that surgery is sometimes needed to reduce the risk of dislocating the same shoulder again, and Mayo Clinic explains that stretched or torn ligaments, damaged tendons or damaged nerves or blood vessels may require surgical repair. Whether it is advised depends on the injury and the person.

Your doctor or physiotherapist will advise when you can return to tasks such as driving or sport. To help prevent dislocations, Mayo Clinic suggests avoiding falls, wearing protective gear in contact sports and exercising regularly to maintain strength and flexibility. A short record of the discharge instructions helps you follow them:

• how long to wear the sling and when to remove it
• which movements are allowed and which to avoid, and for how long
• the date of the next review and of physiotherapy appointments
• the agreed criteria for driving, work and sport
• symptoms that should prompt earlier review, such as numbness, weakness or the shoulder feeling unstable again

09Sources

Where the sources differ

The sources describe recovery time differently. Mayo Clinic says most people regain full use of the shoulder within a few weeks, while the NHS says recovery usually takes 6 to 12 weeks, up to 16 weeks to return fully to some sports, and longer for some people. The difference partly reflects what is being measured, daily use versus full return to sport, and the severity of the injury. Neither figure is a guarantee, and return to activity is decided by the treating team, not by the calendar.

Mayo Clinic gives more detail on causes, complications and nerve or blood vessel damage, while the NHS gives more practical detail on hospital treatment and recovery. Both pages were reviewed in 2026 (May for Mayo Clinic and September for the NHS).

10Summary

In summary

A shoulder dislocation is when the upper arm bone comes out of the shoulder socket, usually after a fall, a blow or a sports injury. It typically causes intense pain, a visible deformity, swelling or bruising and difficulty moving the arm, sometimes with numbness or tingling. It needs emergency care: support the arm, apply ice and do not try to put it back yourself.

In hospital, an X-ray is usually done and a doctor puts the shoulder back under pain relief or sedation, followed by a sling for a few weeks. Physiotherapy helps reduce pain and stiffness and strengthen the shoulder. Recovery usually takes weeks to a few months, the risk of another dislocation is higher afterwards, and surgery is needed only in some cases.
