Acute calcific tendonitis

Calcium crystal diseases

Acute calcific tendonitis is a type of calcium crystal disease. It occurs when calcium crystals, called apatite crystals, deposit in tendons, which can cause sudden attacks of painful inflammation. Symptoms of acute calcific tendinitis include:

  • painful swelling around the joint (most commonly shoulder)
  • bulging tendons due to crystal deposits
  • redness and tenderness around the joint.

Treatment for acute calcific tendonitis can include a range of drugs, joint aspiration and injection, and lavage.

You can find more information about acute calcific tendonitis on our calcium crystal diseases pages.
