What is shoulder impingement?

Shoulder impingement occurs when inflammation, bone spurs, or fluid buildup causes a rotator cuff tendon to be squeezed and rub against a bone.

Causes of shoulder impingement

Each time when you raise your hand above your head, the upper tendon in the rotator cuff (supraspinatus tendon) and the bursa that lies on top of the tendon glide on the underside of the upper end of your shoulder blade (acromion).

  • The underside of the acromion may be rough and rubbing against the bursa and tendon.
  • Repeated overhead arm movements can result in painful inflammation of the bursa (bursitis) and/or the tendon (tendinitis).

Over time, the tendon may wear against the underside of the acromion.

  • Tiny tears may develop.
  • Then, the tendons in the rotator cuff can no longer balance the upward pull of the shoulder muscle (deltoid) on the head of the upper arm bone. This can lead to further damage to the rotator cuff tendon. The weaker the tendon becomes, the more susceptible it is to partial or complete tears.

Treatment for shoulder impingement

You can use RICE, Rest, Iced, Compression and Elevate for home treatment for the time being to see if the symptoms improve.

However, if you have the following symptoms, please seek specialist’s attention.

  • Signs of infection or inflammation.
  • Numbness or tingling sensation to your arms.
  • Shoulder range of motion or strength is limited and does not improve with time.
  • Symptoms do not improve despite RICE method.
  • Symptoms become more severe or frequent.
