For many runners and walkers, tendonitis in the Achilles or posterior tibial tendons can be a frustrating setback. As a physical therapist, I’ve seen how these common injuries can derail your routine, but with the right approach, recovery is entirely possible.

• The posterior tibial tendon and Achilles tendon are crucial for maintaining foot stability and facilitating movement, playing a key role in maintaining balance and proper gait.
• Posterior tibial tendonitis often presents as pain along the inner ankle, swelling, and difficulty with prolonged standing.

• The Achilles tendon, the largest tendon in the body, connects the calf muscles to the heel bone, enabling actions such as walking, running, and jumping. Both tendons are susceptible to overuse injuries, which can cause significant discomfort and impact daily activities, making their care and proper management essential for active individuals.
• Achilles tendonitis, on the other hand, is marked by pain and stiffness at the back of the heel, swelling, and discomfort that worsens with activity. To address tendonitis, start with rest and ice to manage inflammation.

Incorporating physical therapy is crucial; stretching and strengthening exercises can alleviate strain, while a footwear assessment may reveal the need for better support. Manual therapy, dry needling and pain control techniques can also provide relief. As you recover, gradually reintroduce activities to avoid overloading the tendons. There is not a “one size fits all” approach to this injury and proper diagnosis and plan of care modifications and treatments are important to the recovery process.

Preventing future issues involves supportive, cushioned footwear and focusing on strengthening exercises for the feet, calves, and lower legs. Cross-training with low-impact activities can also help maintain fitness without stressing the tendons. Walking barefoot for long distances on the beach (sand) can alter foot mechanics and cause repetitive trauma to these tendons.

Achilles and posterior tibial tendonitis don’t have to put your fitness goals on hold. By understanding the causes, recognizing symptoms early, and following a structured treatment and prevention plan, you can manage these conditions effectively and return to your activities stronger than before. It is common for individuals with this injury to assume it will heal quickly, when in reality if it is ignored, it can persist for months.
