Severe Shoulder Pain & Unable to Lift Your Arm? Know the Possible Causes – By Dr. Balaraju Naidu, Robotic Orthopedic Surgeon, ONUS Robotic Hospitals

Shoulder pain is a common complaint—but when it becomes severe and you are unable to lift your arm, it is not something to ignore.

This symptom can significantly affect daily activities like dressing, combing hair, or reaching overhead. In many cases, it indicates an underlying orthopedic condition that requires timely evaluation and treatment.

Why Can’t You Lift Your Arm?

The shoulder is one of the most mobile joints in the body. This mobility makes it prone to injuries involving muscles, tendons, ligaments, and joints.

When pain is severe and movement is restricted, it usually indicates a structural or inflammatory problem.

Common Causes of Severe Shoulder Pain

1. Rotator Cuff Injury

The rotator cuff is a group of muscles and tendons that stabilize the shoulder.

Injury or tear can cause:

• Severe pain

• Weakness

• Difficulty lifting the arm

• Pain during overhead movement

2. Frozen Shoulder (Adhesive Capsulitis)

Frozen Shoulder is a common cause of progressive stiffness and pain.

Symptoms include:

• Gradual onset of pain

• Severe restriction of movement

• Difficulty lifting or rotating the arm

• Night pain

It is especially common in diabetic patients.

3. Shoulder Impingement Syndrome

Occurs when shoulder tendons get compressed during movement.

Symptoms:

• Pain while lifting the arm

• Pain during overhead activities

• Gradual worsening of symptoms

4. Calcific Tendinitis

Calcium deposits in shoulder tendons can cause:

• Sudden severe pain

• Limited movement

• Difficulty lifting the arm

5. Shoulder Arthritis

Degenerative changes in the joint can lead to:

• Pain and stiffness

• Reduced range of motion

• Difficulty performing daily activities
