Calcific tendinitis
Calcific tendinitis is a build-up of calcium crystals in the rotator cuff tendons that can cause intense shoulder pain, particularly during the resorptive phase.
Key points
The essentials at a glance.
What to look out for, who treats it, and what usually happens next.
-
Calcium deposits form in the rotator cuff, most often in middle age
-
Pain can be severe and sudden when the deposit begins to dissolve
-
Many deposits cause little or no symptoms and resolve spontaneously
-
Ultrasound-guided barbotage (needling and washout) is highly effective
-
Shockwave therapy and keyhole removal are further options
Understanding it
About Calcific tendinitis.
In calcific tendinitis, chalky calcium deposits form within the rotator cuff tendons of the shoulder. The deposit may sit quietly for years, but when the body starts to reabsorb it the shoulder can become abruptly and severely painful - sometimes among the worst pain patients report - with sleep badly disturbed.
Diagnosis is straightforward on X-ray or ultrasound. Treatment options escalate from anti-inflammatory measures and physiotherapy to ultrasound-guided needle barbotage, which washes out the deposit, shockwave therapy, and keyhole surgery for the small number of resistant cases. In the UK you can start with your GP: on the NHS, a routine referral to a specialist clinic often means waiting 20–45 weeks or more to be seen, while a private consultant will typically see you within around two weeks, with any tests arranged soon after.
Frequently asked
Common questions about Calcific tendinitis.
Quick, plain-English answers to what people ask us most.
-
What is calcific tendinitis?
Calcific tendinitis is an infection that develops when bacteria, viruses or other organisms invade the affected tissue and trigger inflammation. Severity varies widely, from a mild, self-limiting illness to a more serious infection that needs prompt treatment. The specific organism responsible, and how quickly it is identified, has a big influence on the best treatment.
-
What causes calcific tendinitis?
Calcific tendinitis is caused by an infectious organism, which may be bacterial, viral or fungal depending on the specific condition. It can spread through close contact, contaminated surfaces, insect bites, or from another site of infection in the body. People with a weakened immune system, chronic illness or certain risk factors are generally more susceptible.
-
What are the symptoms of calcific tendinitis?
Symptoms of calcific tendinitis vary from person to person and depend on how severe the condition is and which structures are affected. Some people notice symptoms gradually over weeks or months, while others experience a more sudden onset. Because symptoms can overlap with other conditions, a proper assessment is important to reach an accurate diagnosis rather than relying on symptoms alone.
-
Is calcific tendinitis serious or dangerous?
Most cases of calcific tendinitis are manageable, especially when identified and treated early, but severity varies from mild and self-limiting to more significant, depending on individual circumstances. Left unassessed, some cases can lead to complications or a longer-term impact on daily life. If you are worried about your symptoms, it is always worth getting them checked rather than waiting.
-
Is calcific tendinitis contagious or can it come back?
Whether calcific tendinitis can be passed on or can recur depends on the specific cause and how well any underlying trigger is managed. Some cases are a one-off, while others can flare again if you are re-exposed to the same trigger or organism. Your clinician can advise on the specific risk of recurrence in your case and any steps that reduce it.
-
Can calcific tendinitis be cured, reversed or prevented?
Outlook varies with calcific tendinitis: some cases resolve completely with treatment, others improve significantly but need ongoing management, and a smaller number become a long-term condition to be controlled rather than cured. Prevention strategies, such as addressing modifiable risk factors, can reduce your chances of developing it or of it recurring, but cannot guarantee against it in every case.
-
How is calcific tendinitis treated?
Treatment for calcific tendinitis is tailored to the individual and depends on severity, underlying cause and personal circumstances. Options can range from simple lifestyle measures, monitoring and conservative treatment through to medication, specialist procedures or surgery in more significant cases. A specialist assessment helps identify which combination of treatments is most appropriate for you.
-
How long does calcific tendinitis last?
The duration of calcific tendinitis varies considerably: some people recover within days or weeks, while others live with a more persistent or recurring condition that needs ongoing management. Response to treatment, how early it is started, and individual factors all influence the timescale. Your clinician can give you a more personalised estimate once your specific circumstances are known.
-
When is surgery needed for calcific tendinitis?
Surgery is not usually the first option for calcific tendinitis and is generally reserved for cases where conservative treatment has not worked, symptoms are severe, or there is a significant structural problem that needs to be corrected directly. The decision depends on your specific findings, symptoms and how they are affecting your life. A specialist consultation is the best way to establish whether surgery is being considered too early, or should be considered sooner rather than later.
-
When should I see a doctor about calcific tendinitis, and how quickly can I be seen privately?
It is worth seeing a doctor about calcific tendinitis if symptoms are persistent, getting worse, or affecting your daily life, rather than waiting to see if they settle on their own. NHS routine referrals to a specialist can currently take anywhere from around 20 to 45 weeks or more depending on your area, whereas a private consultant can typically see you within about 2 weeks. Getting an earlier assessment can help clarify the diagnosis and start the right treatment sooner.
