Shoulder swelling

Swollen shoulder or swelling in or around the shoulder joint can be from a direct impact like a contusion. There may be specific local swelling on the top of the shoulder as in an acromioclavicular (AC) joint sprain, or general swelling in the shoulder joint which would accompany a dislocation or other acute shoulder injury. Swelling can also be through an arthritic joint or a muscle rupture, which can look swollen but can be hard to touch in some cases. Swelling can also occur with a rotator cuff or cartilage injury and can be associated with pain. Some medical conditions through infections or bites can also cause shoulder swelling and can also cause redness.

Swelling can also occur with a rotator cuff or cartilage injury and can be associated with pain. Some medical conditions through infections or bites can also cause shoulder swelling and can also cause redness. Injuries with this symptom are listed below:
  • Rotator Cuff Tear

    Rotator Cuff Tear

    A rotator cuff strain is a tear to any of the four rotator cuff muscles in the shoulder and is common in throwing and racket sports. They are so called because their job is to rotate the arm at the shoulder and provide a supportive cuff around the joint. Rotator cuff tears can range from mild to severe.

  • Dislocated Shoulder

    Dislocated Shoulder

    A dislocated shoulder is a traumatic and painful injury often caused in contact sports or from a fall.

  • AC Joint Separation

    AC Joint Separation

    An AC joint separation or AC joint sprain is an injury to the ligament that holds the acromioclavicular joint together at the top of the shoulder. It is usually caused by fall onto an outstretched arm.

  • Proximal Humerus Growth Plate Fracture

    Proximal Humerus - Fracture

    A growth plate fracture or epiphysis plate fracture occurs at the end of a bone in children before the bone has fully turned from cartilage to hard bone. A proximal humerus fracture occurs in the upper arm, near the shoulder.

  • Clavicle Fracture

    Clavicle Fracture

    A clavicle fracture or broken collar bone as it is also known is a fracture of the clavicle bone which runs along the front of the shoulder to the breast bone or sternum in the middle of the chest.

  • Long Head of Biceps Rupture

    Long Head Biceps Rupture

    The biceps muscle splits into two tendons at the shoulder.The long tendon runs over the top of the humerus bone and can suffer a partial rupture causing pain at the front of the shoulder.

  • Fracture of the Neck of the Humerus

    Fracture Neck of the Humerus

    A fractured neck of the humerus is often caused by falling onto an outstretched hand or a direct impact to the shoulder. It is seen more often in young adults, adolescents and the elderly.

  • Pec Major Tendon Strain (Rupture)

    Pec Major - Strain

    The pectoralis major muscle is a large powerful muscle at the front of the chest. It used to rotate the arm inwards. Its weak point is at the tendon where it attaches to the arm bone.

  • Scapula Fracture

    Scapula Fracture

    A scapula fracture is a break in the shoulder blade bone at the back of the shoulder. This is a relatively uncommon injury, making up only 1% of all fractures.

  • Shoulder Sprain

    Shoulder Sprain

    A shoulder sprain is damage to the shoulder ligaments or capsule which support the glenohumeral or shoulder joint. This may be stretching of the fibers or partial to full tears of the ligaments or joint capsule.

  • Posterior Shoulder Dislocation

    Posterior Shoulder Dislocation

    A posterior shoulder dislocation occurs when the head of the humerus moves backwards out of the socket. This is a rare shoulder injury as most shoulder dislocations are anterior.

  • Deltoid Muscle Strain

    Deltoid Muscle Strain

    An injured Deltoid muscle can cause pain at the front, side or back of the shoulder.

  • Deltoid Contusion

    Deltoid Contusion

    A deltoid contusion is a bruise in the deltoid muscle which is situated on the side of the shoulder. This occurs after a direct impact to the muscle, usually from a hard, blunt object such as a hard ball or an opponents elbow!

  • Shoulder Pain

    Shoulder injuries can be either acute or chronic depending on when they are diagnosed and how long the pain / disability has been felt for. If you are not sure what your injury is why not check out our symptom checker! Or use the links below to view specific shoulder injuries. An acute shoulder injury occurs suddenly either through direct impact, over stretching a muscle, tendon or ligament, overusing a muscle or tendon or twisting of the shoulder joint. The top five most common categories of shoulder injury are listed below.
