Achilles tendinopathy

Overview

Achilles tendinopathy is a condition where the large tendon at the back of your heel becomes painful, swollen, or stiff. This tendon connects your calf muscles to your heel bone and helps you push off your foot when you walk, run, or jump. The condition is usually caused by overuse or repetitive strain.

Yes, Achilles tendinopathy is fairly common, particularly among active middle-aged and older adults, as well as athletes. It is one of the most frequent overuse injuries in running and jumping sports.

It affects people of all ages, but it is most common in middle-aged and older adults who are physically active. It also often affects athletes, especially runners, basketball players, and tennis players.

Symptoms

Common symptoms

• Pain along the back of your heel or lower calf, especially during or after activity.
• Stiffness in the tendon when you get up in the morning or after sitting for a while.
• Swelling or thickening of the tendon.
• Tenderness when you press on the tendon.

Symptoms in children

• Children may have similar pain, but it is often linked to growth spurts. They might complain of a sore heel or limp during or after sports.

Symptoms in older adults

• Older adults may notice a gradual onset of pain, stiffness after sitting, and difficulty walking or climbing stairs. The pain may be less sharp but more persistent.

Causes

Main causes

• Overuse or repetitive strain on the Achilles tendon, often from increasing activity too quickly.
• Tight or weak calf muscles that put extra stress on the tendon.
• Flat feet or other foot and ankle issues that change the way you walk.

Risk factors

• Being middle-aged or older.
• Being male (though it affects women too).
• Participating in sports like running, basketball, tennis, or dancing.
• Wearing shoes with poor support or suddenly changing footwear.
• Training on hard or uneven surfaces.
• Having a high body weight.

When to see a doctor

See a doctor urgently if:

• If you have sudden severe pain, a popping sound, or cannot bear weight on your foot.
• If you have signs of infection like fever, redness, or warmth around the tendon.

Book a routine appointment if:

• If you have persistent pain or stiffness in the Achilles area for more than a few weeks.
• If self-care measures (rest, ice, stretching) are not helping after 2 weeks.

Diagnosis

A doctor will ask about your symptoms, activities, and any recent changes in your exercise routine. They will examine your leg and foot, pressing on the tendon and checking your ankle movement. This is usually enough to make a diagnosis.

Tests that may be done

• Usually no tests are needed. If the diagnosis is unclear or symptoms are severe, your doctor might order an ultrasound or MRI scan to look at the tendon more closely.

What to expect at your appointment

After the exam, your doctor will discuss a treatment plan. This may include rest, exercises, and possibly a referral to a physical therapist. They will also advise you on when to return to your normal activities.

Treatment

The main goal of treatment is to reduce pain and help the tendon heal. Most people get better without surgery. Treatment focuses on rest, exercises to strengthen the calf muscles, and slowly returning to activity. It is important to work closely with your healthcare provider to avoid making the condition worse.

Self-care at home

• Rest from activities that cause pain, but try to stay gently active with low-impact exercises like swimming or cycling.
• Apply ice wrapped in a cloth to the painful area for 15-20 minutes several times a day.
• Gently stretch your calf muscles after warming up (e.g., after a short walk).
• Avoid high-impact activities like running or jumping until the pain is gone.

Medical treatments

Your doctor may recommend physical therapy with specific exercises to strengthen the tendon. They may also suggest orthotic shoe inserts or a heel lift to reduce strain. In some cases, treatments like shockwave therapy or corticosteroid injections (used with caution) might be considered. Medications such as non-steroidal anti-inflammatory drugs (NSAIDs) can help with pain and swelling for a short time, but always follow your doctor's advice. No specific drug names or doses are mentioned here.

When is surgery considered?

Surgery is rarely needed. It may be considered if symptoms do not improve after 6 to 12 months of non-surgical treatment. The type of surgery depends on the damage, and it aims to remove scar tissue or repair the tendon.

Living with this condition

Recovery from Achilles tendinopathy can be slow. You may need to modify your activities for several months. It is important to follow your rehabilitation plan and not rush back to high-impact sports. Listen to your body and gradually increase activity as pain allows.

Lifestyle tips

• Wear shoes with good cushioning and support, especially during exercise.
• Always warm up before exercise and cool down afterward.
• Avoid sudden increases in the intensity, duration, or frequency of your activities.

Diet and exercise

Eating a balanced diet and maintaining a healthy weight can reduce the load on your Achilles tendon. For exercise, try low-impact activities like swimming, cycling, or yoga while you recover. Strengthening your calf muscles with specific exercises can also help prevent recurrence.

Mental health and emotional wellbeing

Living with ongoing pain can be frustrating and may affect your mood or motivation. It is normal to feel discouraged at times. Try to stay positive by setting small goals and celebrating progress. If you feel very low, talk to your doctor or a mental health professional.

Prevention

You can reduce your risk by gradually increasing your activity level, warming up properly, stretching your calf muscles regularly, and wearing suitable footwear. Strengthening exercises for your calves and avoiding overtraining are also helpful. While not all cases can be prevented, these steps can lower your chances.

Complications

If left untreated

• Chronic (long-term) pain and stiffness that can limit your daily activities.
• Thickening of the tendon (chronic tendinopathy).
• Increased risk of a tendon rupture (complete tear), which may require emergency surgery.

Long-term outlook

With proper and consistent treatment, most people recover fully from Achilles tendinopathy. It may take several months, but by working with your healthcare team and being patient, you can get back to your normal activities. The outlook is very good.
