The Achilles tendon, located at the back of the lower leg, is a strong band of fibrous tissue that connects the calf muscles to the heel bone. There are several different types of Achilles tendon injuries. The two most common injuries are Achilles tendonitis and Achilles tendon ruptures. 

When the tendon is injured due to repetitive strain and overuse, it can result in a condition called Achilles tendonitis. This injury is characterized by inflammation of the Achilles tendon, heel and calf pain, thickening of the tendon, ankle and calf stiffness, and a decreased range of motion. In the initial stages of Achilles tendonitis, pain primarily occurs following physical activity, but it can become constant and chronic if the injury is left untreated. 

When the Achilles tendon fully tears, it is known as an Achilles tendon rupture. This usually occurs following a sudden, high-impact injury. Symptoms include a sudden, stabbing pain in the back of the affected leg, a popping or snapping sensation, swelling, and difficulty walking and raising the foot. This condition requires prompt treatment to prevent further damage to the tendon. 

There are a variety of treatments available for Achilles tendon injuries. Achilles tendonitis can often be treated through conservative methods, such as resting, icing, compressing, and elevating the affected foot, wearing orthotics, taking over-the-counter pain medications, and doing gentle stretches. Achilles tendon ruptures may require surgical treatment to avoid reinjury. For more information about Achilles tendon injuries, please consult with a chiropodist.
