The Achilles tendon is the largest and strongest tendon in the human body, connecting the calf muscles, the gastrocnemius and soleus, to the heel bone, or calcaneus. Structurally, it is composed of dense collagen fibers arranged in parallel bundles that provide both strength and flexibility. These fibers allow the tendon to withstand high tension during activities like walking, running, and jumping. The tendon is surrounded by a sheath that helps reduce friction and provides lubrication for smooth movement. Functionally, the Achilles tendon plays a key role in movement and stability. It transmits the powerful force generated by the calf muscles to lift the heel off the ground, enabling push-off during walking or sprinting. It also helps maintain balance and absorb shock during impact. Because of the stress it endures, the Achilles tendon is prone to overuse injuries, especially in athletes and active individuals. If you have Achilles tendon pain, it is suggested that you see a podiatrist for a diagnosis and appropriate treatment.

What Is the Achilles Tendon?
The Achilles tendon is a tendon that connects the lower leg muscles and calf to the heel of the foot. It is the strongest tendon in the human body and is essential for making movement possible. Because this tendon is such an integral part of the body, any injuries to it can create immense difficulties and should immediately be presented to a doctor.
What Are the Symptoms of an Achilles Tendon Injury?
There are various types of injuries that can affect the Achilles tendon. The two most common injuries are Achilles tendinitis and ruptures of the tendon.
Achilles Tendinitis Symptoms
- Inflammation
- Dull to severe pain
- Increased blood flow to the tendon
- Thickening of the tendon
Rupture Symptoms
- Extreme pain and swelling in the foot
- Total immobility
Treatment and Prevention
Achilles tendon injuries are diagnosed by a thorough physical evaluation, which can include an MRI. Treatment involves rest, physical therapy, and in some cases, surgery. However, various preventative measures can be taken to avoid these injuries, such as:
- Thorough stretching of the tendon before and after exercise
- Strengthening exercises like calf raises, squats, leg curls, leg extensions, leg raises, lunges, and leg presses
