The Achilles tendon is the largest and strongest tendon in the human body and connects the calf muscles to the heel bone. Achilles tendon lesions can occur when the tendon is overused, injured or degenerated. Symptoms can include pain, swelling, stiffness, and difficulty moving the foot or ankle. It can also cause weakness and difficulty walking, particularly on uneven surfaces or when going up stairs. Treatment can vary depending on the severity of the injury, but may include rest, ice, compression, and elevation, physical therapy, medication, and in some cases, surgery. #3d #animation #achilles
