What Is a Tendinopathy? Understanding Tendon Pain & How Rehabilitation Helps

Tendon pain is one of the most common reasons people stop sport, modify training, or struggle with day-to-day activities. You might have heard it called “tendonitis”, but in many long-lasting cases the issue is better described as tendinopathy, a change in tendon health and load tolerance rather than a simple short-term inflammation.

At Redrock Physio in St Albans, we see tendinopathy across the full spectrum — from runners with Achilles pain, to desk workers with tennis elbow, to active patients with jumper’s knee, plantar heel pain, or lateral hip pain (gluteal tendinopathy/GTPS). The common thread is usually the same: the tendon has become sensitive to load, and it needs a structured return to strength.

Common Examples We Treat

Tendinopathy can affect many sites. Some of the most common are:

• Tennis elbow (lateral elbow tendinopathy)

• Jumper’s knee (patellar tendinopathy)

• Achilles tendinopathy

• Gluteal tendinopathy / GTPS (lateral hip pain)

• Plantar heel pain (often labelled “plantar fasciitis”, but persistent cases behave similarly to tendinopathy)

(If you want, we can add internal links from each bullet to relevant service sub-pages later.)

Why Tendon Pain Often Doesn’t Settle “On Its Own”

Many people rest until pain eases, then return to normal activity — and the pain returns.

That’s not failure; it’s just how tendons behave:

• Rest can reduce symptoms, but it doesn’t rebuild capacity.

• Tendons usually improve when load is reintroduced progressively, not removed entirely.

• Random “a few exercises” often fail because the dose (load/volume/frequency) isn’t right.

This is why a structured plan matters.

The Redrock Approach: Progressive Loading (Not Random Exercises)

The foundation of tendinopathy rehab is graded loading building tendon capacity over time.

Many modern protocols use heavy slow resistance (HSR) and/or progressive strengthening approaches (with an appropriate starting point and progression).

We typically build rehab in phases:

1) Settle irritability and restore confidence

• Identify the key aggravating loads

• Adjust training/work patterns (not “stop everything”)

• Choose starting exercises that are tolerable

2) Build strength and tendon capacity

• Progressive strengthening (often HSR principles)

• Target the whole kinetic chain (e.g., calf + hip for Achilles; shoulder/forearm for tennis elbow)

3) Reintroduce sport-specific load

• Return-to-run / return-to-jump / return-to-grip progressions

• Gradual exposure to speed, power and volume

4) Reduce recurrence risk

• Better load management habits

• Maintenance strength work

For gluteal tendinopathy specifically, NHS specialist guidance and major trials support education + exercise as first-line management with lasting benefits.

What About Shockwave Therapy?

Shockwave therapy can be a useful adjunct in some chronic, stubborn cases — but it is not a replacement for rehab.

NICE has published HealthTech guidance on extracorporeal shockwave therapy (ESWT) for:

• chronic plantar heel pain (plantar fasciitis) 

• refractory tennis elbow 

• Achilles tendinopathy 

Across these, NICE notes no major safety concerns, but the evidence for effectiveness can be variable/inconsistent depending on the condition and study design, and some guidance emphasises appropriate governance/consent/audit arrangements.

How we position shockwave at Redrock:

• considered when symptoms are persistent and progress has plateaued

• used alongside a progressive loading programme

• explained clearly so expectations are realistic

When Should You Seek Physiotherapy Input?

Consider assessment if:

• tendon pain has persisted beyond a few weeks

• you keep cycling through rest → flare-ups → rest

• it’s affecting training, work or sleep

• you’re unsure what loads are safe vs unhelpful

For tennis elbow, UK specialist pathways emphasise rehab (including loading) and avoiding quick “short-term fixes” that don’t hold up long-term.

How Physiotherapy Helps (What You’ll Get at Redrock)

A tendinopathy physiotherapy assessment typically includes:

• identifying the tendon’s irritability and load triggers

• strength testing and movement analysis relevant to your sport/work

• a staged rehab plan with clear progressions

• advice on pacing and training modification

• (where appropriate) discussion of adjuncts such as shockwave

The goal is simple: restore function, rebuild capacity, and reduce recurrence — with a plan you can actually follow.
