Tightness of the tendons at the back of the leg is very likely to be caused by muscle strain formed after chronic and acute strain of the muscles at the back of the leg, which can usually be relieved by reducing the activities of the leg and giving hot packs, physiotherapy, moxibustion and acupuncture to the leg. If muscle pain worsens or becomes unbearable, oral meloxicam or ibuprofen can be taken to relieve the pain. If varicose veins or bone injuries occur in the lower extremities, they need to be fixed in a cast. The cast is usually fixed for about one month, avoiding the movement of the limb on the ground, and after one month, the cast is removed and proper functional exercise of the joint is performed, which usually does not produce other sequelae. Usually, it is necessary to review the fracture on a regular basis afterwards to avoid premature weight-bearing that may cause the fracture to not heal.
