The Achilles tendon is located on the back side of the ankle and heel, and is a muscle on the back side of the calf, a continuation of the flounder and gastrocnemius muscles, which becomes a tendon that ends at the back of the heel bone, and its role is to maintain balance in the foot and ankle calf position. Usually the Achilles tendon is prone to injury and inflammatory lesions, mainly due to strenuous exercise without adequate warm-up, which may lead to excessive stretching of the Achilles tendon, which is prone to Achilles tendon injury, especially where the Achilles tendon is attached to the heel bone. Frequent outdoor activities and excessive fatigue can lead to localized strain injury and chronic sterile inflammatory lesions in the Achilles tendon and the attachment point of the Achilles tendon and bone, which can manifest as significant pain in the Achilles tendon. After this condition, it is important to stay relaxed and rest, and try to fix it with a brace or ankle cast, so that the Achilles tendon can be completely relaxed and rested to help recovery.
