What are the symptoms of Achilles tendon strain?

The Achilles tendon is the tendon between the heel and the calf. Under normal circumstances, the length of the Achilles tendon is about 15 centimeters. When the human body is exercising, especially walking, the main force comes from the Achilles tendon. If the Achilles tendon is strained or torn, the patient will be unable to walk. After the Achilles tendon is hit hard, or long-term weight-bearing walking, etc., it will induce Achilles tendon strain. So what are the symptoms of Achilles tendon strain?

First, what are the symptoms of Achilles tendon strain? The Achilles tendon is the largest and strongest tendon tissue in the human body, formed by the tendon tissue of the gastrocnemius and soleus muscles. Achilles tendon rupture is a common injury in sports. With the progress of society and the increase in the number of people participating in sports, the proportion of Achilles tendon rupture is also increasing. The pathological changes of the Achilles tendon mainly include inflammatory lesions of the Achilles tendon, chronic injuries of the Achilles tendon, and acute injuries of the Achilles tendon.

Second, there is a very thick, strong and tight tendon between the heel and the calf, which is the Achilles tendon. The Achilles tendon is about 15 cm long and is a large tendon in the human body. It is formed by the fusion of the tendons of the triceps surae (soleus, internal and external heads of the gastrocnemius) about 15 cm above the heel. People's walking, running and jumping rely on this strong tendon. If the Achilles tendon is completely broken, it will be difficult to move.

Third, the Achilles tendon is a large tendon located behind the ankle joint. It connects the Achilles tendon, a muscle group at the back of the calf, to the calcaneus. It is an indispensable tissue for human walking, running, climbing and other movements. Generally, Achilles tendon inflammation is divided into bacterial and aseptic types. However, due to the special reason that the blood supply to the Achilles tendon is relatively insufficient, its healing time is often relatively slow.

What are the symptoms of Achilles tendon strain? The Achilles tendon does not have a true tendon sheath, but is surrounded by peritendinous tissue (fatty interstitial tissue that separates the tendon and the tendon sheath). The early pain of Achilles tendinitis is mainly caused by damage to the tissues around the tendon. When the patient gets up or continues walking, the activity of the tendon in the peritendinous tissue increases, so the pain worsens. The pain may also be worse during training. There is tenderness when pressing the Achilles tendon with fingers. If the patient continues to run despite the pain, the inflammation will spread to the tendon, causing degeneration and fibrosis, resulting in persistent pain that is aggravated by activity.
