Shoulder Impingement: When Everyday Arm Movements Become Painful

Your shoulder is one of the most complex and frequently used joints in the body. From reaching overhead to getting dressed or lifting objects, nearly every arm movement depends on healthy shoulder mechanics. When pain begins to limit these simple actions, shoulder impingement may be the underlying cause.

Shoulder impingement occurs when the tendons of the rotator cuff become compressed or irritated as they pass through the narrow space at the top of the shoulder. Over time, this repeated friction can lead to inflammation, pain, and reduced mobility.

Common Symptoms of Shoulder Impingement

Patients with shoulder impingement often experience:

  • Pain when lifting the arm overhead
  • Discomfort reaching behind the back
  • Shoulder weakness or stiffness
  • Pain that worsens with repetitive use or at night

Ignoring these symptoms can allow inflammation to worsen and may eventually lead to more serious injuries, such as rotator cuff tears.

Conservative Treatment Comes First

Dr. Samuel Koo, MD, MPH believes that even mild or temporary shoulder pain deserves attention. Early evaluation can help prevent long-term damage. Many patients find relief through non-surgical treatments, including:

  • Activity modification
  • Physical therapy to restore strength and flexibility
  • Anti-inflammatory medications or targeted injections

These approaches often allow the shoulder to heal while maintaining joint function.

When Surgery Is Necessary

If symptoms persist despite conservative care, minimally invasive arthroscopic surgery may be recommended. Using small incisions and advanced techniques, Dr. Koo can relieve pressure on the shoulder tendons while preserving surrounding structures. Patients typically experience less pain, faster recovery, and improved shoulder function following arthroscopic treatment.
