As an adjunct to the treatment of tendovaginitis, Tendon Pill mainly treats the local edema and pain associated with tendovaginitis by relaxing tendons and blood, reducing swelling and pain, and promoting the improvement of joint flexion and extension activities. Mild tendovaginitis can be better treated when there are no popping symptoms, but when local hard knots are formed and the flexion and extension of the fingers and toes are impaired, the treatment cannot be better and surgery is needed in time. Surgery is performed to open up the narrow tendon sheath and promote normal functional activity of the tendon sheath. All treatment should be active and standardized under the guidance of a doctor.
