Calcific tendonitis may be caused by:
  • Overuse, repetitive motions
  • Injury

Risk Factors

Your risk of calcific tendonitis of the shoulder may be increased if you:
  • Participate in sports that require repetitive arm use such as baseball, swimming, javelin throwing, and volleyball
  • Have a job that requires repetitive arm use such as painting, carpentry, and welding


Symptoms may include:
  • Sudden onset of pain
  • Intense pain with shoulder movement
  • Stiffness of shoulder
  • Loss of shoulder range of motion
  • Pain that disrupts sleep
  • Tenderness over rotator cuff
  • Loss of muscle mass


You will be asked about your symptoms and medical history. A physical exam will be done. It will assess your range of motion and stability. Images may be taken of your shoulder. This can be done with an x-ray.You may be referred to a specialist. For example, an orthopedic surgeon specializes in bones.


Most cases of calcific tendonitis resolve over time. Talk with your doctor about the best plan for you. Options include the following:

Medical Treatment

Your medical treatment plan will likely include:
  • Nonsteroidal antiinflammatory drugs (NSAIDs)
  • Rest
  • Heat and/or ice
  • A steroid shot directly into your shoulder to decrease inflammation and pain

Physical Therapy

You may be referred to a therapist for treatment. A therapist will use different treatments to decrease the pain and inflammation. Possible treatments include:
  • Ultrasound—a device that uses high energy sound waves to decrease pain in soft tissue
  • Transcutaneous electrical nerve stimulation (TENS)—used to decrease muscle stiffness or spasms
When the symptoms have started to decrease, you will work with the therapist to strengthen your muscles and increase your range of motion.

Lavage Treatment

Lavage may help flush out the calcium deposits. A needle is placed directly into the shoulder. Normal saline is injected through the needles. The deposits are then broken up for removal.

Shock Wave Therapy

This therapy breaks up deposits by sending sound waves to the shoulder. The body can then reabsorb the smaller pieces. This should decrease symptoms.


In some cases, surgery may be done to remove deposits. The procedure is called arthroscopy . It uses small incisions and instruments to view the joint and remove the deposits.
