Rotator cuff tendonitis

Rotator cuff tendonitis, also known as subacromial impingement, is a common condition that causes shoulder pain, swelling, and localized irritation when lifting or rotating the arm.

What causes shoulder impingement?

Overuse and repetitive overhead movement are the primary causes. The condition is particularly prevalent in athletes involved in swimming, tennis, throwing sports, and weightlifting, as well as individuals in manual trades (such as painters, decorators, and carpenters).

Common symptoms

  • Mild, localised shoulder aching during early stages, particularly when reaching overhead or behind your back
  • Sharp pain when lifting the arm between 60 and 120 degrees (the 'painful arc')
  • Persistent pain at rest or at night, making it difficult to lie comfortably on the affected side
  • Progressive joint stiffness, loss of arm strength, and difficulty with daily overhead tasks

 

How is rotator cuff tendonitis diagnosed?

Diagnosing rotator cuff tendonitis involves a comprehensive clinical examination by your consultant to assess shoulder mobility, muscle strength, and specific pain triggers while ruling out referred neck pain or cervical nerve irritation.

How is it treated?

Treatment aims to reduce inflammation, create space within the joint, and restore full overhead function.

Treatment routes for rotator cuff tendonitis

The majority of cases resolve without surgery. Conservative management includes resting from aggravating overhead activities, taking non-steroidal anti-inflammatory drugs (NSAIDs) under medical advice, and completing a targeted physical therapy program. Physiotherapy focuses on strengthening the rotator cuff and stabilizing the shoulder blade (scapula) to improve posture and joint mechanics. Subacromial corticosteroid injections may also be offered to rapidly calm severe inflammation and facilitate rehabilitation.

Recovery from rotator cuff tendonitis

0–2 weeks

Pain management and gentle movement

A shoulder sling is worn for comfort during the first week or two. Focus on controlling swelling with ice and prescribed medication. Gentle pendulum exercises and movement of the elbow, wrist, and hand begin immediately. Dressings should be kept clean and dry, with stitches checked or removed around 10 to 14 days.

2–6 weeks

Restoring range of motion

The sling is discontinued, and guided physical therapy shifts toward progressive stretching exercises to restore overhead reach and rotational flexibility.

6–12 weeks

Strengthening and functional recovery

Targeted strengthening exercises for the rotator cuff and scapular muscles are introduced. Most patients notice significant improvement in pain and daily function between 2 to 4 months post-surgery, with complete tissue recovery taking up to a year.
