Shoulder Tendinitis – What Is It?

Shoulder tendinitis is an injury to the shoulder that occurs most commonly when attempting to lift something too quickly, lifting something that is too heavy or falling on an outstretched arm.  The sudden stress on the tendon causes microtears which lead to inflammation of that tendon. Shoulder tendinitis is often mistaken with shoulder tendinosis.  Shoulder tendinosis involves degeneration of the collagen in the tendon due to chronic overuse.  To get the best possible treatment outcomes it is important to distinguish between the two.1,2,3

What Are The Symptoms?

Shoulder tendinitis symptoms may include:

  • Pain
  • Stiffness/reduced range of motion
  • Weakness
  • Clicking with movement

How Serious Is It?

Shoulder tendinitis for some is a mild injury, for others it can lead to a chronic and very painful condition.  The severity of the initial injury, timeliness of seeking treatment, proper diagnosis, proper treatment and overall health are all factors that influence how severe of a problem shoulder tendinitis is. 

What Are The Treatment Options?

One of the main reasons it is important to differentiate between tendinitis and tendinosis is because they should be treated differently.  Going to see a qualified chiropractor, physical therapist, orthopedist, physiotherapist, etc. for an assessment can help tremendously in pain reduction and recovery time.  A few of the treatment options for shoulder tendinopathy include, but aren’t limited to:

  • Mechanical loading (exercises)
  • Rest
  • Injections (PRP)
  • Massage
  • IASTM (Instrument Assisted Soft Tissue Mobilization)
  • Biomechanical assessment/interventions
  • Injections (Corticosteroids)

How Long Will It Take To Heal?

Factors that influence how long a shoulder tendinopathy will take to heal include things such as age, extent of the injury, overall health, appropriateness of treatment, etc.  Shoulder tendinitis when treated early can be resolved in several days to 6 weeks. 2  When left untreated shoulder tendinopathies can become chronic issues.  Although it may seem unrelated, your overall health condition often plays a large role in the healing process.  It is important to get adequate sleep and maintain a healthy diet and exercise routine. 

What Should I Expect?

When receiving care for a shoulder tendinopathy the doctor or therapist will ask you questions and give you a shoulder exam to determine the best possible treatment.  The doctor may perform a movement assessment to identify any possible faulty movement patterns.  Once a thorough exam is performed the doctor will be able to determine the best possible treatment strategy.  It is important to follow any care instructions given by your doctor as strengthening and stretching exercises are often crucial to the healing process.
