What is it?

Your rotator cuff is a group of four muscles and tendons that help lift and rotate your arm. A strain happens when one of these muscles or tendons gets overstretched or irritated—often from overuse, a sudden movement, sporty activities or simply wear and tear over time.

How it happens

Rotator cuff strain is common in people over 40, especially those doing repeated overhead activities—like painters, swimmers, or tennis players. It can also occur from lifting something heavy or falling on your shoulder. Sometimes, the strain develops slowly from poor posture or repeated small stresses over time.

 

What you might feel

  • A dull ache or sharp pain in the shoulder
  • Pain that worsens at night, especially when lying on that side
  • Weakness when lifting or reaching
  • Limited movement, especially when raising the arm overhead or behind your back

How physiotherapy helps

A physiotherapist will assess your shoulder’s movement, strength, and function. Based on the findings, your treatment may include:

  • Manual therapy to reduce stiffness and improve joint movement
  • Targeted exercises to strengthen the rotator cuff and surrounding muscles
  • Postural correction to reduce ongoing strain
  • Stretching to restore flexibility
  • Activity modification advice to prevent further irritation

What you can do

  • Rest from painful movements, especially overhead activities
  • Apply ice early on to reduce pain or swelling
  • Begin your physio treatment as guided—consistency is key
  • Maintain good posture while sitting, working, or sleeping

Will you need surgery?

Most people get better without surgery, often within 6–12 weeks of starting treatment. Surgery may be considered if a tendon is fully torn or if non-surgical treatments don’t help.

Recovery

With the appropriate treatment, most people improve within 6–12 weeks. Starting early can prevent further damage and help you return to daily activities or sport safely.
