Pain in the back of your heel or lower calf can make even simple activities like walking, climbing stairs, or exercising uncomfortable. One of the most common causes of this type of pain is Achilles Tendinitis, an overuse injury that affects the largest tendon in the body. Without proper treatment, the condition can worsen over time and may even increase the risk of an Achilles tendon rupture.
At Foot & Ankle Care of Colorado, we provide expert diagnosis and treatment for Achilles Tendinitis, helping patients reduce pain, restore mobility, and safely return to their daily activities.
What Is Achilles Tendinitis?
The Achilles tendon connects your calf muscles to your heel bone and plays a vital role in walking, running, jumping, and pushing off your foot.
Achilles Tendinitis occurs when this tendon becomes irritated and inflamed, typically due to repetitive stress or overuse. It is especially common among runners, athletes, and individuals who suddenly increase their level of physical activity.
While Achilles Tendinitis often develops gradually, early treatment can help prevent long-term damage to the tendon.
What Causes Achilles Tendinitis?
Several factors can contribute to Achilles Tendinitis, including:
- Sudden increases in exercise intensity or duration
- Running on hills or uneven terrain
- Tight calf muscles
- Flat feet or abnormal foot mechanics
- Wearing worn-out or unsupportive shoes
- Repetitive jumping or sprinting activities
- Returning to sports too quickly after an injury
- Aging, which can reduce tendon flexibility
Many cases develop from a combination of these factors rather than a single event.
Common Symptoms of Achilles Tendinitis
Symptoms of Achilles Tendinitis often begin gradually and may include:
- Pain along the back of the heel or lower calf
- Stiffness, especially first thing in the morning
- Tenderness when touching the tendon
- Swelling around the tendon
- Pain that worsens with activity
- Limited ankle flexibility
- Thickening of the tendon over time
Early symptoms may improve with rest but often return once activity resumes.
What Happens If Achilles Tendinitis Is Left Untreated?
Ignoring Achilles Tendinitis can allow the tendon to continue deteriorating.
Without proper treatment, complications may include:
- Chronic tendon pain
- Reduced strength and flexibility
- Tendon thickening
- Achilles tendinosis (degenerative tendon changes)
- Partial tendon tears
- Complete Achilles tendon rupture
Seeking care early can often prevent these more serious injuries.
How Achilles Tendinitis Is Diagnosed
At Foot & Ankle Care of Colorado, we begin with a comprehensive evaluation to determine the cause of your symptoms.
Your assessment may include:
- Review of your medical history and activity level
- Physical examination
- Evaluation of ankle flexibility and strength
- Gait analysis
- Assessment of foot alignment
- X-rays if bone abnormalities are suspected
- Ultrasound or MRI when additional information about the tendon is needed
An accurate diagnosis allows us to develop the most effective treatment plan for your condition.
Treatment Options for Achilles Tendinitis
Most patients with Achilles Tendinitis improve with conservative treatment when care begins early.
Treatment may include:
Activity Modification
Temporarily reducing high-impact activities allows the tendon time to heal while maintaining overall fitness through low-impact alternatives.
Physical Therapy
Targeted stretching and strengthening exercises improve flexibility, restore tendon function, and reduce the likelihood of future injuries.
Supportive Footwear
Shoes with proper cushioning and support can reduce stress on the Achilles tendon during walking and exercise.
Custom Orthotics
For patients with abnormal foot mechanics, custom orthotics may improve alignment and decrease strain on the tendon.
Anti-Inflammatory Treatments
Your provider may recommend appropriate methods to help reduce pain and inflammation based on your individual needs.
Walking Boots or Bracing
In more severe cases, temporary immobilization may allow the tendon to recover.
