The pulling sensation when the tendon is recovering from exercise is normal, which may be related to the soft tissue of the injured part has not been fully recovered, long time braking tendon contracture, incorrect activity and other reasons. 1. Normal phenomenon: the recovery time after tendon injury usually takes 4-6 weeks, and rehabilitation before full recovery will cause the tendon area to be stimulated by pulling again, resulting in pulling sensation, which is a normal phenomenon; and due to the need for prolonged braking after tendon injury, tendon contracture will occur to varying degrees, and the pulling sensation may occur when rehabilitating the tendon again. 2. Incorrect tissue repair and rehabilitation: after tendon injury, the body carries out scarring repair, that is, the fibrous tissue replaces the original tendon, the fibrous tissue itself is relatively tough, which will lead to a decrease in the elasticity of the overall tendon tissue, and a pulling sensation may also occur. In addition, incorrect posture during rehabilitation and excessive training beyond the tolerance of the tendon can also lead to a pulling sensation. There may also be other reasons for the pulling sensation during tendon recovery exercises, so it is recommended to go to the hospital in time, complete the examination to clarify the cause of the disease, and then give targeted treatment or therapy under the guidance of the doctor.
