Understanding Tendinopathy: Why Your Tendon Pain Keeps Coming Back

Tendinopathy: Not What You Think It Is

If you have been told you have tendinitis – inflammation of a tendon – the diagnosis is probably wrong. Research over the past two decades has revealed that most chronic tendon problems involve degeneration rather than inflammation. The correct term is tendinopathy, which describes structural changes in the tendon including collagen disorganisation, increased water content, and growth of new but abnormal blood vessels and nerves. This distinction matters enormously because it changes the treatment approach entirely.

Anti-inflammatory medications and cortisone injections target inflammation that is largely absent in chronic tendinopathy. While they may provide short-term pain relief, they do not address the structural tendon changes and may actually impair healing. Multiple cortisone injections have been shown to weaken tendons over time, increasing rupture risk. The most effective treatment for tendinopathy is progressive loading through specific exercises – and this is where physiotherapy becomes the most important intervention.

Why Tendons Fail to Heal on Their Own

Healthy tendon tissue is composed of tightly organised collagen fibres arranged in parallel, like cables in a bridge. When tendinopathy develops, this organised structure breaks down. The collagen fibres become disorganised, and the tendon fills with proteoglycans that attract water, causing the tendon to swell. New blood vessels and nerves grow into the tendon, which is paradoxically part of the problem because these nerves are a source of pain.

The key insight is that rest alone does not reverse these structural changes. While rest reduces pain temporarily, the tendon remains structurally compromised and the pain returns as soon as loading resumes. This is why many Penang residents experience recurring tendon pain – they rest until the pain settles, then return to their normal activities, which immediately overloads the still-weakened tendon. Breaking this cycle requires a fundamentally different approach: progressive mechanical loading that stimulates the tendon to rebuild its collagen structure.

The Loading Continuum for Tendon Rehabilitation

Modern tendinopathy treatment follows a loading continuum that progresses through several phases. Isometric exercises are the starting point – holding a sustained muscle contraction without joint movement. For example, for Achilles tendinopathy, standing on your toes and holding for 30 to 45 seconds. Isometric loading reduces pain immediately and begins the process of stimulating collagen production. Isotonic exercises follow, involving movement through range against resistance, such as slow heel raises.

Eccentric loading – slowly lowering against resistance – was historically considered the gold standard for tendinopathy treatment, but current evidence suggests that heavy slow resistance training combining both concentric and eccentric phases is equally effective. The key principles are that the exercises must be heavy enough to create mechanical stimulus, slow enough to stress the tendon, and performed consistently for a minimum of 12 weeks. Your home visit physiotherapist will determine the appropriate starting point based on your tendon’s current tolerance and progress the loading systematically.

Common Tendinopathy Sites and Specific Treatment

Achilles tendinopathy is extremely common in Penang, affecting runners, badminton players, and anyone who increases their activity level too quickly. Treatment centres on progressive calf loading exercises performed with the knee straight to target the gastrocnemius and with the knee bent to target the soleus. Patellar tendinopathy, or jumper’s knee, affects the tendon below the kneecap and requires heavy slow squatting programmes.

Gluteal tendinopathy causes pain on the outside of the hip, often misdiagnosed as bursitis, and is particularly common in post-menopausal women. Treatment involves hip abductor strengthening while avoiding positions that compress the tendon against the bone, such as crossing legs or lying on the affected side. Rotator cuff tendinopathy requires specific shoulder loading exercises at the correct angle to target the affected tendon. Your home visit physiotherapist will diagnose which tendon is affected, identify the contributing factors, and design a condition-specific loading programme.

Adjunct Treatments and What to Avoid

Several adjunct treatments can support the exercise-based foundation of tendinopathy treatment. Shockwave therapy delivers acoustic waves to the tendon, stimulating cellular healing responses and providing pain relief. Evidence supports its use for chronic tendinopathy that has not responded adequately to exercise alone. Dry needling of associated muscle trigger points can reduce the muscle tension that overloads the tendon.

Treatments to approach with caution include cortisone injections, which provide short-term relief but may worsen long-term outcomes. Complete rest should be avoided – modified activity that reduces the aggravating load while maintaining some tendon loading is preferable. Passive treatments like ultrasound and TENS have limited evidence for tendinopathy and should not replace exercise therapy. Your home visit physiotherapist in Penang will use adjunct treatments strategically to manage pain and support your exercise programme, not as standalone interventions.

Preventing Tendinopathy Recurrence

Once tendinopathy has resolved, preventing recurrence requires understanding and addressing the factors that caused it. The most common cause is a sudden increase in load – increasing running distance too quickly, starting a new sport without adequate preparation, or changing job duties to include more repetitive tasks. The general guideline is to increase training load by no more than 10 percent per week.

Maintaining tendon health through ongoing loading exercises is equally important. Performing your tendon-specific exercises two to three times per week after recovery maintains the collagen quality that treatment has restored. Your home visit physiotherapist will create a maintenance programme and educate you on recognising the earliest signs of tendon irritation – morning stiffness at the tendon site and pain during the warm-up phase of exercise – so you can increase your loading exercises and modify your activities before a full-blown tendinopathy develops again.
