Tendon pain shows up all over the body — the Achilles, just below the kneecap, the outside of the elbow, the side of the hip — and yet it tells the same story every time. If you've been told to rest a painful tendon and it hasn't worked, this article explains why, and what does. Understanding tendinopathy is genuinely empowering, because the treatment that works is largely in your own hands.
What is tendinopathy?
Tendinopathy is the umbrella term for a painful, overloaded tendon. Despite the old “-itis” ending (as in “tendonitis”), which implies inflammation, research over the past two decades has shown that a painful tendon isn't mainly inflamed. Instead, it's a tendon that has been loaded more than it could cope with, leading to changes in its structure and how it handles load (Cook and Purdam, 2009). That single shift in understanding changes everything about treatment.
The tendon continuum
A helpful way to picture it is as a continuum. A tendon can move from healthy, to a reactive (irritable, overloaded) state, and — if overload continues — towards more established change. The encouraging part is that this isn't a one-way street: with the right load management, a tendon can move back towards a healthier, more pain-free state (Cook, Rio, Purdam and Docking, 2016). You're not simply stuck with it.
Why “rest” isn't the answer
Tendons are living tissue that adapt to the loads placed on them — load them sensibly and they get stronger and more tolerant. Complete rest does the opposite: it de-loads the tendon, which loses capacity, so that when you return to activity the same load now overwhelms it and the pain comes straight back. Rest can settle an angry tendon briefly, but on its own it doesn't build the tolerance you need.
Why loading is the treatment
Progressive loading — gradually and deliberately exercising the tendon — is what rebuilds its capacity and reduces pain. It's the common thread through the evidence for every tendinopathy, whether that's the Achilles, the patellar tendon, the hamstring, the gluteal tendons or the elbow. The skill is in the dosage: enough load to drive adaptation, not so much that you flare it.
The loading ladder
Rehabilitation usually climbs a ladder. It often starts with isometric holds, which can ease pain and let you load safely; progresses to heavier, slower strength work that drives adaptation; and then, for active people, adds spring-like, sport-specific loading before a graded return to full activity. A pain-monitoring rule guides each step: some discomfort during and after exercise is acceptable as long as it settles within about 24 hours and isn't worse the next morning.
The tendon family (and where to read more)
The same principles run through the common tendinopathies we treat: patellar tendinopathy (jumper's knee), Achilles tendinopathy, proximal hamstring tendinopathy, gluteal tendinopathy (greater trochanteric pain syndrome), rotator cuff tendinopathy and tennis elbow. Each has its own quirks — for instance, some are sensitive to compression and dislike deep stretching — but all are managed by progressive loading. Our individual articles on each go into the specifics.
A word on injections and passive treatments
Hands-on treatment and other passive approaches can help you feel more comfortable, but they support loading rather than replace it. It's also worth knowing that for some tendon problems, repeated corticosteroid injections can lead to worse outcomes over the longer term — tennis elbow being a well-studied example. Loading remains the foundation.
When to seek help
When to seek help. See a clinician if tendon pain has hung around for more than a few weeks, keeps returning when you train, or is limiting your activity. Seek urgent review for a sudden, sharp pain or a “pop” in a tendon with difficulty using the limb, as that can signal a rupture rather than a tendinopathy.
Frequently asked questions
Is tendinopathy the same as inflammation?
Not mainly. A painful tendon is better understood as overloaded, with changes in its structure and load tolerance, rather than classically inflamed (Cook and Purdam, 2009).
Should I rest my tendon?
Complete rest usually backfires, because the tendon loses capacity. Modifying load while progressively loading the tendon works better.
How long does a tendinopathy take to settle?
Often a few months of consistent loading. Tendons adapt slowly, so patience and consistency matter more than intensity.
Do injections help?
They may give short-term relief for some, but they don't build the tendon's capacity, and for certain tendons repeated injections can worsen long-term outcomes. Loading is the mainstay.
Can I keep training?
Usually in a modified form, guided by the 24-hour rule — discomfort that settles by the next day is generally acceptable.
How BPR can help
At BPR we'll confirm which tendon is involved and where it sits on the continuum, then build you a progressive loading programme dosed to your tendon and your goals. You can book an assessment at bpr.rehab.
