Achilles tendon is the thick, strong band of tissue that connects your calf muscles to your heel bone. It plays a key role in many everyday activities like walking, running, jumping, and even standing on your toes. Because the Achilles tendon works hard every day, it is prone to wear and tear. Repeated stress, sudden increases in activity, or wearing improper footwear can cause small tears or inflammation. This often leads to pain and swelling, a condition called Achilles tendinitis. If ignored, the tendon can become weak or stiff, making movement painful and limiting your mobility. In severe cases, it may even partially or completely rupture, which requires medical treatment. You can protect your Achilles tendon with these simple habits: * Warm up and stretch your calves before exercise. * Wear supportive shoes and avoid hard surfaces. * Increase workout intensity gradually. * Rest and ice your heel if sore or swollen.
