Achilles Tendonitis: The Symptoms, Causes & How Arch Support Can Help

Achilles tendonitis is a condition characterised by inflammation of the Achilles tendon, which is a large tendon connecting the calf muscles to the back of the heel bone. This inflammation can cause pain, swelling, and discomfort in the affected area.

The Achilles tendon plays a crucial role in activities like walking, running, and jumping. When it is inflamed, these movements can become painful and challenging. Achilles tendonitis is often a result of overuse, improper footwear, or sudden increases in physical activity.

It’s important to address Achilles tendonitis symptoms because if left untreated, it can lead to more severe issues like tendon degeneration or tears. Continuous stress on the inflamed tendon may weaken it over time, increasing the risk of more serious injuries. Early intervention, which may include rest, ice, stretching exercises, and proper footwear, is crucial to manage the condition and prevent further damage to the Achilles tendon. Seeking medical advice is recommended for proper diagnosis and a tailored treatment plan.

Types of Achilles Tendonitis

Insertional Achilles Tendonitis

Insertional Achilles Tendonitis is a type of Achilles tendonitis that primarily affects the lower part of the tendon, where it attaches to the heel bone (calcaneus). In this condition, the inflammation and pain occur at the point where the tendon inserts into the back of the heel.

This type of tendonitis is often associated with bone spurs, which are bony protrusions that may develop at the insertion point. Insertional Achilles Tendonitis is commonly seen in individuals who engage in activities that repeatedly stress the tendon, such as running or jumping.

Non-insertional Achilles Tendonitis

Non-insertional Achilles Tendonitis is characterised by inflammation and degeneration of the middle portion of the Achilles tendon. Unlike insertional tendonitis, there is typically no involvement of the insertion point on the heel bone. This type of tendonitis is more common in younger, active individuals and is often related to overuse and microtears within the tendon.

Non-insertional Achilles Tendonitis may be associated with swelling, thickening of the tendon, and pain in the middle portion of the tendon, just above the heel. It is crucial to differentiate between these two types for proper diagnosis and to tailor an appropriate treatment plan for effective management.

Achilles Tendonitis Symptoms

Pain in the Back of the Heel

Individuals with Achilles Tendonitis symptoms often experience pain in the back of the heel, near the tendon. This pain is commonly described as a dull or sharp ache and may intensify during physical activities like walking, running, or climbing stairs. The discomfort may be more pronounced in the morning or after periods of inactivity. It’s essential to pay attention to any persistent heel pain, especially if it worsens with activity, as it could be an early sign of Achilles Tendonitis.

Difficulty Walking

Achilles Tendonitis symptoms can lead to difficulty walking, especially when the affected foot pushes off the ground during each step. The pain and stiffness in the Achilles tendon may cause a noticeable limp, and individuals may find it challenging to engage in activities that require pushing off with the foot, such as running or jumping. Recognising and addressing this difficulty in walking early on is crucial to prevent further stress on the tendon and promote a faster recovery.

Swelling, Tenderness, and Warmth of the Achilles Tendon

Swelling, tenderness, and warmth around the Achilles tendon are common symptoms of Achilles Tendonitis. The affected area may appear visibly swollen, and there could be tenderness when touching or applying pressure to the tendon. The warmth is a result of the inflammatory process.

Monitoring for these signs is important as they indicate an ongoing inflammatory response. Early recognition of these symptoms is vital for prompt intervention, helping to prevent the progression of Achilles Tendonitis and reduce the risk of complications. Seeking medical advice for a proper diagnosis and tailored treatment plan is recommended if these symptoms persist.

What Causes Achilles Tendonitis?

Overuse or Excessive Physical Activity

Engaging in activities that put repetitive stress on the Achilles tendon, such as running, jumping, or intense sports, can lead to overuse and contribute to the development of Achilles Tendonitis.

Improper Footwear

Wearing shoes with inadequate support, insufficient cushioning, or improper fit can increase the risk of Achilles Tendonitis. Footwear that does not provide proper arch support or places excessive strain on the Achilles tendon may contribute to the development of the condition.

Sudden Increase in Physical Activity

Rapidly increasing the intensity, duration, or frequency of physical activity, especially without proper conditioning or warm-up, can strain the Achilles tendon and lead to inflammation.

Tight or Weak Calf Muscles

Imbalances in the calf muscles, such as tightness or weakness, can affect the mechanics of the Achilles tendon. Tight calf muscles may increase the strain on the tendon, while weak muscles may not provide adequate support.

Age & Gender

Achilles Tendonitis is more common in active individuals, and age can be a factor. Middle-aged and older individuals may be more prone to the condition. Additionally, men are generally at a higher risk than women.

Foot Structure & Biomechanics

Certain foot structures or biomechanical issues, such as flat feet or high arches, can alter the normal load distribution on the Achilles tendon, making it more susceptible to stress and inflammation.

Medical Conditions & Medications

Conditions such as arthritis or certain medications, particularly fluoroquinolone antibiotics, may increase the risk of Achilles Tendonitis.

Inadequate Warm-up or Stretching:

Skipping warm-up exercises or neglecting proper stretching before physical activity can leave the Achilles tendon less prepared for the demands of exercise, making it more susceptible to injury.

Identifying and addressing these risk factors can help individuals reduce their chances of developing Achilles Tendonitis. Adopting proper warm-up routines, wearing appropriate footwear, and gradually increasing the intensity of physical activities are essential preventive measures. If symptoms persist or worsen, seeking professional medical advice is recommended for a thorough evaluation and tailored treatment plan.

What are the risk factors for Achilles tendonitis?

Age:

Achilles Tendonitis is more commonly seen in individuals as they age. As people get older, their tendons may become less flexible and more prone to injury. The aging process can also lead to decreased blood supply to the tendons, making them more susceptible to inflammation and strain.

Bone Spurs:

Bone spurs are bony projections that may develop at the insertion point of the Achilles tendon on the heel bone. These spurs can cause irritation and inflammation, contributing to the development of Achilles Tendonitis. They are often associated with insertional Achilles Tendonitis, a specific type of the condition.

Gender:

Men are generally at a higher risk of developing Achilles Tendonitis compared to women. This gender difference may be due to various factors, including differences in muscle mass, strength, and biomechanics. Men often engage in activities or sports that put more stress on the Achilles tendon, increasing their susceptibility to the condition.

High Impact Sports or Activities:

Participation in high-impact sports or activities, such as running, basketball, or soccer, increases the risk of Achilles Tendonitis. The repetitive stress and strain on the Achilles tendon during these activities can lead to overuse, microtears, and inflammation.

Certain Medical Conditions:

Certain medical conditions, such as arthritis and psoriasis, can increase the risk of Achilles Tendonitis. These conditions may affect the health of the tendon or contribute to inflammation. Additionally, individuals with diabetes may be at a higher risk due to impaired blood flow and nerve function.

Obesity:

Excess body weight places additional stress on the Achilles tendon during activities like walking or running. This increased load can contribute to the development of Achilles Tendonitis, especially in individuals who are overweight or obese.

Physical Traits:

Biomechanical factors, such as having flat feet or high arches, can alter the normal mechanics of the foot and ankle, affecting the distribution of forces on the Achilles tendon. These physical traits may increase the risk of developing Achilles Tendonitis.

Poor Stretching or Warming Up Prior to Exercise:

Inadequate warm-up and stretching routines before engaging in physical activity can leave the Achilles tendon less prepared for the stress of exercise. Insufficient flexibility may contribute to strain and an increased risk of tendon injury.

Worn-Out Shoes:

Wearing shoes with worn-out soles or inadequate support can impact the biomechanics of the foot and contribute to Achilles Tendonitis. Proper footwear is crucial for maintaining the stability and proper alignment of the foot during activities.

Identifying and addressing these risk factors can help individuals take preventive measures to reduce the likelihood of developing Achilles Tendonitis. Incorporating proper warm-up exercises, choosing appropriate footwear, and managing underlying medical conditions are essential for maintaining tendon health and preventing injury.

How Arch Support Thongs Can Help

Arch support thongs, also known as orthotic or supportive flip-flops, can be beneficial in preventing and managing Achilles Tendonitis foot support. Providing the necessary support and reducing strain on the Achilles tendon. Here are some key benefits:

1. Improved Arch Support:
   • Arch support thongs are designed with built-in arch support, which helps maintain the natural alignment of the foot. This added support can reduce excessive pronation (rolling inward) of the foot, which, in turn, minimises stress on the Achilles tendon.
2. Shock Absorption:
   • Many arch support thongs come with cushioned soles or shock-absorbing materials. This feature helps absorb the impact forces during walking or other weight-bearing activities, reducing the strain on the Achilles tendon and providing additional comfort.
3. Even Distribution of Pressure:
   • Arch support thongs are designed to distribute pressure evenly across the foot. This helps prevent localised pressure points on the Achilles tendon, reducing the risk of irritation and inflammation.
4. Stabilisation of the Foot and Ankle:
   • Proper arch support contributes to the stabilisation of the foot and ankle. This stability is crucial in minimising excessive movement that could otherwise place additional stress on the Achilles tendon.
5. Promotion of Proper Biomechanics:
   • Arch support thongs encourage proper biomechanics by supporting the natural structure and function of the foot. This can help individuals with high arches or flat feet maintain a more neutral foot position, reducing strain on the Achilles tendon.
6. Reduction of Overpronation:
   • Overpronation, where the foot rolls excessively inward during walking or running, can contribute to Achilles Tendonitis. Arch support thongs help control overpronation, mitigating the associated strain on the Achilles tendon.
