Shockwave treatment for tendinitis usually takes four weeks. Tendovaginitis is a chronic, sterile inflammation of the tendon sheath caused by mechanical friction strain, and the main treatment methods are conservative treatment and surgery. Conservative treatment is safer, but the cycle is long and the effect is slow. Surgical treatment is effective, but the damage is big and the cost is high. The application of extracorporeal shockwave therapy has a quick effect and low recurrence rate. The treatment cycle is generally four weeks, seven days between each two treatments, and different hospitals need to make appropriate adjustments for different conditions of patients. Shock wave treatment of tenosynovitis must be carried out under the guidance of a doctor, can not be self-treatment, so as not to affect the adverse consequences.
