Achilles Tendinitis
Moderate
Achilles tendinitis is an overuse condition affecting the Achilles tendon, the strong tendon connecting the calf muscles to the heel. The tendon is heavily involved in walking, running, jumping, and pushing the foot downward. Repetitive loading can cause pain, tenderness, and swelling near the heel. Symptoms often develop gradually rather than after one major injury. Although most cases can be managed without surgery, recovery may take several weeks or months, particularly when the tendon has been repeatedly overloaded.

When to Seek Medical Attention
Achilles tendinitis is usually not an emergency, but persistent pain should be assessed to prevent worsening injury. Seek medical evaluation for increasing pain, swelling, or difficulty walking. Prompt assessment is important after a sudden pop or snap, sudden severe pain, or inability to push off or bear weight because an Achilles tendon rupture may have occurred.

Foot Pain
Muscle Weakness
Causes 1
The most common cause is repeated or excessive loading of the Achilles tendon. A sudden increase in running, walking, jumping, or other physical activity can exceed the tendon’s ability to adapt. Tight calf muscles can increase strain on the tendon, and running on hard surfaces may contribute. Less commonly, an acute injury can damage the tendon. Repeated stress without adequate recovery can maintain inflammation and pain and may increase the risk of more significant tendon damage.
Sedentary Lifestyle
Risk Factors
Risk factors include a sudden increase in exercise intensity or duration, frequent running or jumping, tight calf muscles, and activities performed on hard surfaces. Athletes and physically active people may be particularly affected. Inadequate recovery between strenuous activities can also contribute to repeated tendon loading. Previous Achilles tendon problems may increase the likelihood of recurrent symptoms. Appropriate progression of activity and attention to calf flexibility and tendon conditioning can help reduce excessive mechanical stress.
Diagnosis
Diagnosis is based on a patient's medical history,
symptoms, physical examination and, when necessary,
laboratory or imaging investigations.
Diagnosis is generally based on the symptoms and physical examination. A healthcare professional may assess the location of pain, tenderness, swelling, tendon function, calf strength, and the ability to walk or push off the foot. Imaging is not always required, but ultrasound or MRI may be considered when the diagnosis is uncertain, when a tendon tear is suspected, or when surgery is being considered. Imaging can help distinguish tendinitis or tendinopathy from a more significant tendon injury.
Prevention
Key Prevention Tips
Gradually increase the amount and intensity of physical activity rather than making sudden changes
Allow adequate recovery after strenuous exercise and address tight calf muscles with an appropriate stretching or conditioning program
Choosing suitable footwear and reducing repeated high-impact activity when symptoms begin may help prevent worsening
Alternating high-impact exercise with lower-impact activities such as cycling or swimming can reduce tendon loading
Persistent pain should be assessed before returning to intense sport or exercise
Prevention Guidance
Gradually increase the amount and intensity of physical activity rather than making sudden changes. Allow adequate recovery after strenuous exercise and address tight calf muscles with an appropriate stretching or conditioning program. Choosing suitable footwear and reducing repeated high-impact activity when symptoms begin may help prevent worsening. Alternating high-impact exercise with lower-impact activities such as cycling or swimming can reduce tendon loading. Persistent pain should be assessed before returning to intense sport or exercise.
Reminder: Prevention recommendations should be tailored to your personal health status and risk factors.
