Frequently Asked Questions

What are the main symptoms of Achilles Tendinitis?

Achilles tendinitis typically causes pain in the posterior part of the ankle, precisely where the tendon attaches to the heel bone. Sufferers often experience morning stiffness, with the first steps out of bed being particularly painful, though discomfort may decrease with movement.

For a complete overview, see the comprehensive guide to foot and ankle pain.

Is complete rest the best treatment for Achilles Tendinitis?

No, complete rest is generally considered counterproductive for long-term Achilles tendon healing. While it might offer temporary relief, the tendon needs gradual mechanical loading to recover its capacity to withstand stress and prevent the problem from returning.

How should I approach movement and exercise if I have Achilles Tendinitis?

Modern science advocates for a progressive return to movement, emphasizing gradual mechanical loading and eccentric exercises to promote tendon recovery. It is crucial to begin movement progressively and seek specialist help if pain is severe.

Who is most susceptible to developing Achilles Tendinitis?

Achilles tendinitis is common among athletes, particularly recreational runners, but it’s not exclusive to them. Individuals who walk a lot, work standing for many hours, or wear inadequate footwear can also develop this condition, significantly affecting daily life.

When should I seek professional help for Achilles Tendinitis?

You should seek specialist help from a trusted doctor or physical therapist if your pain is severe or significantly impacts your daily activities. A professional can provide an accurate diagnosis and guide you through an effective, personalized rehabilitation program.

Achilles Tendinitis: When Every Step Becomes a Challenge

When the Achilles heel becomes truly vulnerable

Achilles tendinitis is inflammation of the tendon connecting the calf muscle to the heel bone, causing posterior ankle pain, morning stiffness, and discomfort with initial movement. Achilles tendinitis is one of the most common problems among those who practice sports or simply walk a lot during the day. The pain manifests in the posterior part of the ankle, precisely where the tendon attaches to the calcaneus.

Those who suffer from it often describe a sensation of morning stiffness. The first steps upon getting out of bed can be particularly painful. The discomfort tends to decrease with movement, but may return after periods of intense activity.

According to epidemiological studies, this condition affects approximately 9% of recreational runners every year (Source: Van Dijk et al., British Journal of Sports Medicine, 2011). But it doesn’t only concern athletes: even those who work standing for many hours or wear inadequate footwear can develop this problem.

Daily life is significantly affected. Climbing stairs, walking uphill, or even just standing on tiptoes becomes difficult. Many people are forced to modify their habits, avoiding activities they previously practiced regularly.

Absolute rest: an understandable but counterproductive temptation

Faced with pain, the most spontaneous reaction is to stop completely. It is common practice to suspend all physical activity and wait for the discomfort to pass on its own. For years it was believed that rest was the best solution for any tendon problem.

Even many healthcare professionals have traditionally recommended total immobilization. Rigid braces, weeks of inactivity, and waiting for “nature to take its course” have long been the standard approach.

Anti-inflammatories are often used to manage acute pain. They seem to provide immediate relief, which reinforces the idea that rest is the right path. However, today we know that more effective approaches exist for long-term healing.

This method may work for very mild injuries, but often the problem returns as soon as normal activity is resumed. The tendon, having remained inactive for weeks, has not recovered its capacity to withstand loads and mechanical stress.

What modern science teaches us about tendons

Research from the last twenty years has revolutionized the understanding of tendon problems. The Achilles tendon, in particular, responds better to gradual mechanical stimuli rather than complete rest.

The 2018 Cochrane Review demonstrated that eccentric exercises are superior to rest alone in treating Achilles tendinopathies (Source: Cochrane Database of Systematic Reviews, 2018). These exercises allow the tendon to reorganize its fibers more efficiently.

Controlled loading stimulates the production of new and better quality collagen. It’s as if the tendon “learns” again to sustain the stresses of daily life. This process takes time – usually 8 to 12 weeks – but the results are more lasting.

Acute inflammation, when present, is only an initial phase of the healing process. The real challenge is in the subsequent phase, that of tissue repair. This is where guided movement makes the difference compared to simply waiting.

International NICE guidelines recommend an active approach from the early stages, always under professional supervision (Source: NICE Guidelines, 2020).

How to return to movement without worsening the situation

The first step is to assess pain intensity on a scale from 0 to 10. If discomfort during daily activities exceeds 5, a specialist evaluation is advisable before starting any exercise program.

For those who can move with mild or moderate pain, the golden rule is progressivity. Start with simple plantar flexion movements against gravity, 2-3 sets of 15 repetitions, twice a day. Pain must remain tolerable during and after exercise.

Avoid surfaces that are too hard for walking or running. Asphalt is less suitable compared to natural terrain or treadmills with good cushioning. Footwear choice is also crucial: shoes with a slightly raised heel (3-4 mm) can reduce tension on the tendon in the initial phase.

Ice after activity can be useful for controlling any increase in pain, but it should not become the only management tool. 15 minutes of application is sufficient.

Pay attention to warning signs: progressively increasing pain, marked swelling, difficulty walking normally. In these cases, it is necessary to stop and consult a professional.

The right time for specialized help

Achilles tendinitis may seem like a simple problem, but its management requires specific skills. Every tendon has unique characteristics and every person responds differently to treatments.

A specialized physical therapist can evaluate factors that often go unnoticed: running biomechanics, possible muscular imbalances, joint stiffness that may have contributed to the problem. These evaluations are fundamental for preventing relapses.

Manual treatment, combined with specific exercises, accelerates healing times. Techniques such as manual therapy, progressive eccentric exercises, and education on optimal loading are part of an integrated and evidence-based approach.

Don’t wait for the pain to become unbearable. The sooner you intervene correctly, the better the results. Achilles tendinitis, if neglected, can become chronic and much more difficult to resolve.

A physiotherapy program will allow you not only to overcome the current problem, but also to acquire the skills to prevent it in the future.
