How Do I Tell If My Shoulder Is Dislocated?

A shoulder dislocation is a serious injury that can be both painful and disabling. Because the shoulder is the most mobile joint in the human body, it's also one of the easiest to dislocate. Whether it happens during sports, a fall, or a sudden force, recognizing the signs of a dislocated shoulder early is essential for getting the right treatment and avoiding long-term damage.

What Happens During a Shoulder Dislocation?

A dislocated shoulder occurs when the top of the upper arm bone (humerus) slips out of its normal position in the shallow shoulder socket (glenoid). This can happen in different directions—most often forward (anterior dislocation), but also backward or downward. In some cases, supporting tissues such as ligaments, tendons, and the joint capsule can also be stretched or torn.

Common Signs of a Dislocated Shoulder

Recognizing a dislocated shoulder usually isn’t difficult because the symptoms are often intense and immediate. Here are the key signs to watch for:

• Severe Shoulder Pain: Most people feel immediate and intense pain at the moment of dislocation. The pain often worsens with movement.
• Visible Deformity: The shoulder may look visibly out of place, with an unusual contour or bulge. The affected arm may appear longer than the other.
• Inability to Move the Arm: You may not be able to move the shoulder at all or only with extreme pain.
• Swelling and Bruising: Swelling can occur rapidly, and bruising may develop shortly after the injury.
• Muscle Spasms: The muscles around the joint may spasm in response to the injury, increasing discomfort.
• Numbness or Tingling: If nerves are affected, you may feel numbness, tingling, or weakness in the arm or hand.

What to Do If You Suspect a Dislocation

If you suspect that your shoulder is dislocated, it’s important to seek immediate medical attention. Do not try to pop the shoulder back into place yourself—this can cause further damage to surrounding nerves, blood vessels, or bone. Instead:

• Keep the arm as still as possible and use a sling if available.
• Apply ice to reduce swelling and ease pain.
• Avoid eating or drinking in case surgery or sedation is needed.

Confirming the Diagnosis

At a medical facility, a doctor will examine your shoulder and typically order imaging tests like X-rays or an MRI to confirm the dislocation and assess for any additional injuries. Once confirmed, they will likely perform a procedure to gently move the joint back into place, followed by immobilization and physical therapy.

When in Doubt, Get It Checked Out

Shoulder injuries should never be ignored, especially when there is intense pain, immobility, or visible deformity. Even if the joint pops back in on its own, it’s important to get evaluated. Untreated dislocations can lead to recurring instability, arthritis, or nerve damage.
