Calcific tendonitis is a common source of shoulder pain and can be a frustration given the severity of pain and the duration of symptoms. However, the news is not all bad! On a positive note, the vast majority of patients do find relief with nonsurgical treatments for this condition. In fact, studies have shown about 75 percent success with simple steps for treatment. While treatment often takes 3 to 6 months, there are typically improvements without having to undergo a surgical procedure.
