Tendon pain is stubborn. It warms up while you exercise, then bites the next morning, and neither pushing through nor resting completely seems to fix it. In this guide, we explain what is really going on inside an irritated tendon, when it is safe to keep training, when to ease off, and when tendonitis physiotherapy in Wigan and the surrounding towns is the quickest route back to running, riding and lifting.
Tendonitis vs. tendinopathy: why the name matters
Tendonitis is the word most people arrive with, so it is the word we will use through most of this article. Strictly speaking, though, the ending “itis” means inflammation, and research over the past two decades has shown that most stubborn tendon pain is not primarily inflammatory at all. The more accurate name is tendinopathy: a change in the structure of the tendon that develops when it is loaded harder or more often than it can currently tolerate.
Why does the label matter? Because the two problems respond to different things. A freshly irritated, reactive tendon may settle with a short period of sensible load management and simple pain relief. A tendon that has been grumbling for months has usually started to change at a cellular level, and that kind of tendon does not respond well to rest, ice and anti-inflammatory gels alone. It needs to be rebuilt, gradually and deliberately, through loading.
This is the most common mistake we see at our clinic in Chorley: people treating a long-standing tendon problem as if it were a fresh inflammation. The pain eases with every rest, returns with every run, and the cycle repeats for months. Working out which stage your tendon is in is the first step to breaking that cycle.
Why complete rest can make your tendon worse
Tendons are living tissue, and like muscle they adapt to the demands you place on them. Load a tendon sensibly and it gets stronger. Stop loading it altogether and it quietly loses capacity. That is why total rest so often backfires: the pain calms down because you are no longer asking anything of the tendon, but the tendon itself is now weaker than when you stopped.
Then comes the familiar story. After four weeks off, you feel fine, so you return to your old routine at your old level. Your tendon, now less tolerant of load than before, flares up faster than it did the first time. Many of the runners and gym-goers who travel to see us from Wigan and Bolton have been around this loop two or three times before they book in. It matters especially at this time of year, when late-summer mileage peaks ahead of the autumn 10K and half-marathon season and Achilles complaints spike with it.
The alternative is what physiotherapists call relative rest. You remove the spike that stirred the tendon up, perhaps hill sprints, a sudden jump in mileage or a new class at the gym, while keeping the loading your tendon can tolerate.
A useful rule of thumb
Pain up to around 3 or 4 out of 10 during activity is generally acceptable, provided it settles back to your normal baseline within 24 hours. Pain that climbs day on day is your signal to scale back further and get assessed.
The science of tendon loading (and what it means for your training)
If rest does not rebuild a tendon, what does? The evidence points firmly at progressive loading: exercise that is demanding enough to stimulate the tendon to adapt, introduced in stages that respect how irritable it currently is. A well-built programme usually moves through three types of work.
01Isometric holds
Pushing or holding against resistance without movement, for example a heavy mid-range calf hold, can reduce tendon pain in the short term and is a safe starting point when the tendon is at its most irritable.
02Heavy, slow resistance
Slow, controlled strength work, such as calf raises or leg presses performed over several seconds per repetition, is what actually stimulates the tendon to remodel and strengthen. This is the engine room of tendon rehab.
03Energy storage and release
Tendons behave like springs. Hopping, bounding and faster movements are reintroduced last, bridging the gap between the gym and the demands of your sport.
The honest part: tendon remodelling is slow. Meaningful structural change takes weeks, and a tendon that has been painful for a year will not be fixed in a fortnight. The encouraging part is that most people can keep training in some form throughout, and pain usually starts to improve well before the tendon has finished adapting.
Achilles, patellar, gluteal: the three tendons we treat most
Almost any tendon can be overloaded, but three account for most of the tendon problems that come through our doors.
The Achilles
The classic sign is stiffness in the first few steps of the morning that eases once you get moving. We see it most in runners who have increased mileage, pace or hill work quickly, including plenty of parkrunners from Haigh Woodland Park in Wigan and Astley Park in Chorley. If running is your trigger, our guide to avoiding common running injuries pairs well with this article.
The patellar tendon
Pain just below the kneecap, aggravated by stairs, squats, jumping and pushing hard on the pedals. It is common in team sport players and in gym-goers who have ramped up their leg sessions faster than their tendons could keep up with.
The gluteal tendons
Pain over the bony point on the outside of the hip, often worse when lying on that side at night or standing on one leg. It is most common in women over 40, in keen walkers, and in horse riders, who load these tendons every time they sit in the saddle.
Different tendons, same underlying principle: the tendon has been asked to do more than it can currently tolerate, and the answer is to restore its capacity rather than simply silence the pain.
What a tendon rehab plan looks like at NV Physiotherapy
Every tendon programme at NV Physiotherapy starts with a thorough assessment. We take a detailed history of your training, work and daily loading, test the strength and capacity of the muscle and tendon, and establish which stage the problem has reached. Targeting the cause, not merely the symptoms, is the foundation of everything we do.
From there, your plan typically moves through three phases. First we calm the tendon down, using activity modification, isometric loading and, where appropriate, hands-on treatment such as manual therapy and sports massage to ease tight, overworked muscle around the tendon. Next we build the tendon back up with progressive strength work, adjusted week by week according to how it responds. Finally, we return you to sport, reintroducing speed, spring and volume in a structured way so the problem does not simply come back.
You can read more about how we treat tendon problems on our tendonitis physiotherapy page, or explore our sports injury physiotherapy if your tendon trouble is part of a bigger picture. Our ground-floor clinic in Chorley has two private treatment rooms and is an easy drive from Wigan, Horwich and Leyland, with appointment times that fit around work and training.
