What Are The Common Causes Of Shoulder Pain?

Shoulder Pain is nothing strange to happen to any of us. Some of us may only feel pain on the shoulders while others might also feel the pain on the neck as well as on the shoulders. Before we talk a lot further about shoulder pain, it is important to have some basic knowledge about the anatomy of our shoulders.


Our shoulders have three bones on each side. The three bones are collarbone, shoulder blade, and upper arm bone. Our shoulders also consist of muscles, joints, tendons, and ligaments. The muscles are useful to move the bones. The joints contribute in making the shoulder easy to move while the tendons (which attach the shoulder muscles to the bones) help the muscles in moving the bones. The ligaments which attach the three shoulder bones all together stabilize the bones. The description indicates that it takes a coordinated activity among all parts of the shoulder to enable the shoulder to move.


The shoulders are very flexible in movements. When the shoulders are in a fit condition, we will find it easy to move our shoulders up, down, forward, backward, and in rotation (clockwise and anticlockwise). That’s why they are called the most flexible joints in our body. But the flexibility also makes the shoulders very unstable. The volatility makes it easily troubled and injured. It results in a condition that we call shoulder pain.

Shoulder Pain  

The pain on our shoulders can be classified based on the cause. Some of the common causes are: bursitis, frozen shoulder, dislocation, fracture, etc.


Bursitis is also called impingement syndrome. It happens due to excessive use of the shoulders. The symptoms are: 

  • Pain in the upper arm and shoulders.
  • Pain increase when moving and lifting the arms over the head.
  • Sleep disruption due to leaning on the troubled shoulder.

Frozen Shoulder

Frozen Shoulder is also called adhesive capsulitis. Diabetes or thyroid problem may increase the risk of having frozen shoulder. The symptoms of frozen shoulder are:

  • The pain starts slowly but gradually. 
  • At the beginning, you start to feel pain when you move your shoulder.
  • After a week or even months, the pain will lessen but then the shoulder become stiffer.
  • The shoulder movement will be limited.
  • Discomfort and stiffness can interfere sleep during the night time.


Osteoarthritis does not usually occur to people until they reach middle age. The common symptoms of arthritis on the shoulders are:

  • Swelling on the joint.
  • The pain starts slowly but become worse over time.
  • The shoulder feels stiff and painful to move.


Fracture means there are broken bones or broken part of bones. Fracture usually happens as a result of a trauma or collision injury such as a motorcycle accident.

The symptoms of fracture are:

  • Extreme pain, bruises and swelling around the shoulder.
  • Limited movement of the shoulder.
  • In some worse case, the bones seem out of place.
