The ache that won't settle
You know the pattern. Your heel or your elbow is stiff first thing in the morning, it loosens up once you're moving, and then by evening it's sore again after a day on your feet or at a keyboard. It doesn't feel like a proper injury because nothing swelled up and nothing gave way. It just persists, week after week, in a way a pulled muscle usually doesn't.
This is a common way for tendon problems to show up, whether it's the Achilles at the back of the ankle, the tendons around the elbow, or the ones crossing the shoulder. The pain often isn't dramatic. It's the fact that it keeps coming back that tells you something.
What a tendon is built to do
A tendon is the tough, fibrous cord that connects muscle to bone. Its job is to transmit force: when your calf muscle contracts, the Achilles tendon pulls on your heel bone and your foot pushes off the ground. It has to be strong enough to handle repeated, high loads without stretching much, which means it's made of densely packed collagen fibres rather than the more elastic, blood-rich tissue of muscle.
That density is useful for load-bearing, but it comes at a cost. Tendons have a much poorer blood supply than muscle. Less blood flow means fewer of the nutrients and repair cells that tissue needs to heal quickly, which is part of why tendon injuries behave so differently from a muscle strain.
Why the repair takes months, not days
When a tendon is overloaded, whether from a sudden increase in running, a change in your job that has you gripping tools all day, or simply years of repetitive movement catching up with you, the collagen fibres develop small areas of damage. Repairing them means laying down new collagen and gradually organising it back into strong, aligned fibres.
That process runs on a biological timescale measured in weeks and months, not days. A twisted ankle ligament or a strained calf muscle often settles within a few weeks. A tendon problem, left to its own devices, can rumble on for far longer, because the tissue rebuilding itself is slower and less forgiving of interruption.
This is why a tendon injury can feel more frustrating than a more painful one. There's often no single dramatic moment of injury to point to, and no clear finish line either.
Why complete rest often isn't the answer
It's tempting to stop using the area altogether until it feels better. But tendons respond to load. Some controlled, gradual use is usually part of what helps the new collagen organise itself into strong, functional tissue, rather than a disorganised patch that flares up again the moment you go back to normal activity.
The difficulty is judging how much is too much. Too little load and the tendon doesn't rebuild well. Too much, too soon, and you aggravate the very damage you're trying to repair. Getting that balance right, and adjusting it as things change, is where a lot of people get stuck managing it alone.
Where an osteopath fits into this
An osteopath can assess how you're moving and loading the affected area day to day, not just at the point of pain. Often a tendon under strain is being asked to compensate for something else: a stiff joint nearby, an uneven gait, a posture held for hours at a desk. Treatment aims to ease the surrounding strain and support the area as it heals, working alongside the gradual return to activity rather than instead of it.
All our osteopaths at Notts Osteopathy are registered with the General Osteopathic Council. If your pain came on suddenly with significant swelling, or a joint won't bear weight at all, that needs a doctor's assessment rather than an osteopathy appointment.
