Shoulder Pain

Shoulder Pain
Shoulder Pain.

The body's only 360-degree joint — which makes it more complex, and more prone to problems. Here's a full guide to symptoms, causes, tests, treatment, and rehab.

§ 01Definition

What Is Shoulder Pain?

Shoulder pain — key symptoms illustration

Shoulder pain occurs when a problem develops in the muscles, ligaments, bursa, or nerves around the shoulder joint. It is usually caused by a joint disorder or rotator cuff tendon damage.

The shoulder is the only joint in the body capable of 360-degree rotation, which makes it structurally complex — and just as prone to problems.

360°The only joint in the body capable of full-range rotation. Complex structure = why precise diagnosis is essential.
§ 02Symptoms · 03

Key Symptoms

01Limited ROM

Limited Range of Motion

Sharp pain when raising the arm overhead or reaching behind the back; a catching sensation at certain angles

02Night Pain

Night Pain

Pain that worsens at night while lying down, more than during waking hours, disrupting sleep

03Radiating

Radiating Pain

Pain that extends beyond the shoulder, causing tingling down to the elbow or fingertips

§ 03Two Main Causes

Main Causes of Shoulder Pain

01Frozen Shoulder

Frozen Shoulder

Adhesive Capsulitis

A condition in which the joint capsule and ligaments around the shoulder become stiff due to inflammation and fibrosis.

  • Shoulder pain begins gradually
  • Difficulty changing clothes or reaching into a back pocket
  • In severe cases, the arm can no longer be raised
  • Often believed to resolve on its own, but pain can persist for about two years
Getting appropriate treatment early is important for restoring function

02Impingement Syndrome

Shoulder Impingement Syndrome

Rotator Cuff Disorders

An umbrella term covering conditions such as rotator cuff tears, calcific tendinitis, and bursitis.

  • The rotator cuff consists of four tendons surrounding the shoulder joint
  • Connects the shoulder blade and upper arm bone, providing stability and movement
  • Pain results from full or partial tendon tears
  • Inflammation and calcification lead to impingement against the acromion, causing bursitis
Bursa inflammation increases friction between bone and muscle, worsening the syndrome

Rehab
§ 06Rehab · 03 Muscle Groups

Rehabilitative exercise therapy

Treatment that analyzes the root cause of frozen shoulder and shoulder impingement syndrome to correct movement patterns and posture. Essential not only for acute pain relief but also for preventing recurrence and rehabilitation.

01Pectoralis Major · Minor
Chest Area

Pectoralis Major · Minor

Stretches and relaxes tightened chest muscles
To prevent the shoulders from rounding forward
02Serratus Anterior
Underarm Area

Serratus Anterior

Strengthening exercises to keep the shoulder blade close to the chest wall
Key to stability when raising the arm
03Rhomboids · Trapezius
Around the Shoulder Blade

Rhomboids · Trapezius

Exercises for the supporting muscles behind the shoulder
Corrects overall shoulder alignment
