What is Mouse Shoulder?

Mouse shoulder refers to pain on the shoulders that comes about due to using your computer with a mouse without the appropriate arm support. The condition can develop over weeks or months.

The repetitive strain injury (RSI) results from constant repetitive movements in a limited area and can lead to pain on your upper back, neck, and shoulder.

Mouse shoulder may also be referred to as work-related upper limb disorder or repetitive strain injury.

How Does Mouse Shoulder Occur?

If you work in an office setting, you probably spend hours every day with one arm extended on your mouse, dragging and clicking items. According to the Canadian Center for Occupational and Health Safety, we use the mouse three times more than the keyboard.

Repetitive use of the mouse is common when you are working or playing video games.

If you have set up an ergonomic workstation, the mouse could be too high or too low. The workstation could also be set up in a way that your arm has little or no support during the day.

When the mouse is too low, you will constantly be extending your arm towards it. On the other hand, if it’s too high, you will frequently be tensing the muscles in your shoulder and upper arm.

Over time, the stress on your arm can pile up and lead to a repetitive strain injury. This is what happens with the case of a mouse shoulder.

What Causes Arm Pain from Using Mouse?

There are various reasons why you may experience a mouse shoulder.

To begin, when using a mouse, you make small, focused movements with your fingers and hands. Over time, the small muscles that enable the focused movements can get fatigued. The fatigue can lead to tension of larger muscle groups that try to compensate.

The shoulder and shoulder blade are attached to the body through different muscles that insert into the base of the skull, neck, ribcage, and the spine. When you hold a mouse with the arm held away from the body, the muscles contract as they support the weight of the extended hand. Sitting in this position for several hours without frequent variations can lead to muscle weaknesses and pain.

Apart from using a mouse, similar repetitive strain injuries can occur if you engage in repetitive activities such as performing a predetermined set of manual labor tasks or using industrial machinery in a precise manner.

Common Symptoms of Mouse Shoulder

Below are the common mouse shoulder symptoms:

  • Painful cysts or nodules around your tendons and joints
  • Headaches
  • Loss of strength in the hands
  • Muscle spasms
  • Pain on the wrists
  • Stiffness or burning sensation in your arms or shoulders
  • Tingling or numbness in your hands and fingers
  • Pain that extends down the arms into the hands
  • Pain and tightness on your shoulder blades and upper back
  • Pain in one shoulder (the one that uses the mouse)

In most cases, you will experience a few of these symptoms. If the pain is not addressed on time, it can affect the overall quality of your life.
