What is Calcific Tendinitis?
Calcific tendinitis is a condition where calcium deposits build up within the tendons of the rotator cuff in the shoulder. This can lead to pain, inflammation, and reduced movement in the shoulder joint. The exact cause of why this problem occurs is an area of ongoing research.
The condition most commonly affects people between the ages of 30 and 60. In many cases, the calcium deposits are present without symptoms but when they become inflamed or begin to break down, significant pain can occur.
Where Does it Happen?
Calcific deposits most commonly form in the supraspinatus tendon, one of the key rotator cuff tendons of the shoulder. However, other rotator cuff tendons can also be affected.
Key Characteristics of Calcific Tendinitis
Symptoms often vary depending on the stage of the condition, but may include:
- Acute onset of severe shoulder pain, often without trauma (i.e waking up one morning with severe shoulder pain)
- Pain that is typically worse at night
- Pain when lying on the shoulder
- Pain with lifting or reaching overhead
- A general feeling of being unwell
Diagnosis

Diagnosis is based on a combination of clinical assessment and imaging. A physiotherapist or doctor may refer you for:
- X-rays, which often clearly show calcium deposits
- Ultrasound or MRI, which can help assess the extent of inflammation and rule out other shoulder issues
Stages of Calcific Tendinitis
The condition typically progresses through three stages:
- Formative phase – Calcium slowly builds up in the tendon, often without symptoms
- Resorptive phase -The body begins to break down the calcium; this is often the most painful phase
- Post-calcific phase – The tendon heals and symptoms begin to settle
Management of Calcific Tendinitis
Many cases are managed non-surgically and respond well to a combination of rest, activity modification, and physiotherapy. The treatment approach depends on the stage and severity of symptoms.
Non-Surgical Options:

- Pain management – anti-inflammatory medication (as advised by your doctor), and avoiding/modifying aggravating activities
- Physiotherapy – To restore movement and strengthen the shoulder without further irritating the tendon
- Shockwave therapy – Sometimes used to stimulate breakdown and resorption of the calcium deposits
- Corticosteroid injections – Can help reduce inflammation in more severe or persistent cases
Surgical Intervention
Surgery is an option for individuals who fail to see improvement in symptoms after non- operative management- this is sometimes the case when the calcium deposits in the shoulder are large. Arthroscopic removal of the deposit is typically performed.
Summary
Calcific tendinitis of the shoulder is a treatable condition that can cause significant pain. Early diagnosis and a structured rehab program are essential to reduce pain, improve function, and prevent long-term complications. If you’re struggling with shoulder pain and suspect calcific tendinitis, book an appointment with one of our physiotherapists for a detailed assessment and tailored treatment plan.
