The Deltoid muscle is the large muscle on the top & outside of the shoulder. Although not a common injury, an injured Deltoid can result in pain at the front, side or back of the shoulder. A contusion is more common and occurs from direct impact or trauma to the muscle. On this page: Deltoid …
Front shoulder pain
The pectoralis major muscle is a large powerful muscle at the front of the chest. It is used to rotate the arm inwards. Its weak point is where the tendon attaches to the arm bone, and a strain or rupture can happen here when it is put under stress, when weight training for example. Symptoms of this shoulder injury include pain and swelling at the front of the shoulder.
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. This shoulder injury is more common in older athletes and can cause pain down the arm and swelling in the joint.
A clavicle fracture, or broken collarbone as it is also known, is a fracture of the clavicle bone. The clavicle runs along the front of the shoulder to the breastbone or sternum in the middle of the chest, and can be fractured by a fall. The fracture normally happens towards the middle of the bone but can also happen near the shoulder. The pain will be intense and medical help is needed immediately.
The Clavicle, or collarbone, has a number of muscle attachments along its length. The tendons that attach the muscles to the front of the shoulder and collarbone can become painful and inflamed through overuse. This injury is particularly found in athletes who do a lot of throwing, such as cricketers. Read more on the symptoms and the treatments of this injury below.
Biceps tendinopathy (or biceps tendonitis) is inflammation or more likely degeneration of the long head of the biceps muscle causing pain at the front of the shoulder. It is not a particularly common injury, but excessive weight training or overuse is a potential cause.
The Pectoralis Major tendon is weakest where it inserts into the arm or humerus bone. Common sports that can inflame the tendon include racket sports, rowing, swimming and weight training, and the pain when performing these activities will probably have increased over a period of time. Resting from these sports is essential to recovering from this shoulder injury. Read more on the symptoms and treatments below.
Subacromial bursitis has similar symptoms to Supraspinatus tendinitis, with shoulder pain over a 60-degree arc when the arm is lifted sideways. The subacromial bursa is a sack of fluid over the tendon which helps facilitate movement. This can become trapped, especially in sports where the arm is regularly at or above shoulder level. Resting from these activities helps stop the pain, and once pain-free, you can start doing rehabilitation exercises.
Shoulder Tendonitis or Tenosynovitis is a degenerative condition of any of the tendons surrounding the shoulder joint. This is usually the rotator cuff tendons but it can also occur in the biceps and triceps tendons. The shoulder pain usually comes on gradually and is due to repetitive movements and overuse. It is common in those with poor posture and those who use the joint a lot, like athletes who throw and manual workers.
The glenoid labrum is a fibrous ring of tissue which attaches to the rim of the glenoid shallow hole or socket of the shoulder blade where the ball of the humerus or arm bone sits. When this tissue tears, it creates general shoulder pain and weakness in the joint. This shoulder injury is often caused by repetitive movement such as overhead throwing, so resting from these activities will help to ease the pain
