The natural course of calcific tendinitis consists of four stages: formation, resting, absorption, and recovery. The most severe pain occurs during the absorption stage. While some patients experience natural absorption of the calcium within one to two years, the recurring severe pain during this period makes daily life difficult, and the posture adopted to protect the shoulder can lead to the secondary development of adhesive capsulitis. Early treatment is crucial as it can also progress to tendon rupture. It is a wise choice to shorten the calcium absorption period and prevent complications through treatment. In Korean medicine, acute pain during the calcium absorption phase is viewed as a state where sticky waste products block the pathways of Qi and blood, causing extreme stagnation of these elements. If left untreated, the body's proper energy is depleted, and the functions of the liver and kidneys further weaken, leading to reduced recovery capacity. At Dongjedang, we induce immediate circulation of Qi and blood during the acute pain phase using acupuncture and pharmacopuncture, while in the chronic stage, we lead a gradual recovery by fundamentally clearing remaining adhesions and waste products using thick needles and fire needles.
