Why Some Tendon Problems Refuse to Settle
If you have ever dealt with a stubborn tendon problem, whether it is tennis elbow, Achilles pain, or a persistently irritated shoulder, you know how frustrating it can be.
You rest it. It starts to feel a little better. You try to return to your favourite sport, exercise routine, work activity, or hobby, and then the familiar ache returns.
The usual explanation is often straightforward:
“You must have overdone it at the gym.”
“It is probably repetitive strain from work.”
“You just need to rest it for a while.”
Physical workload and repetitive movement certainly matter. Tendons respond to the demands we place on them, especially when those demands increase too quickly or exceed the tendon’s current capacity.
However, physical loading does not always tell the whole story.
If you experience one tendon problem after another, or if a single issue refuses to improve despite a well-designed rehabilitation plan, it may be helpful to step back and look at the bigger picture.
Your tendons do not exist in isolation. They are living tissues influenced by your overall health, metabolism, hormones, medications, recovery, and genetics.
Here are several less obvious factors that may be influencing your tendon health behind the scenes.
1. Genetics: Your Tendon Blueprint
Have you ever noticed that some people can suddenly begin an intense exercise program and seem to tolerate it without difficulty, while others carefully follow a gradual plan and still develop tendon pain?
Part of the difference may come down to genetics.
Tendons are made primarily of collagen, a strong connective tissue that allows them to transmit force, store energy, and tolerate repeated loading.
Just as people inherit differences in height, hair colour, or body shape, we may also inherit differences in how our bodies produce, organize, and repair collagen.
Some people may naturally have tendons that are more resilient. Others may have tendon tissue that is slightly more sensitive to changes in workload or slower to recover after repeated stress.
This does not mean that tendon problems are inevitable or that you are limited by your genetics.
It simply means that your body may require a more gradual and patient approach to building strength, capacity, and tolerance.
2. Metabolic Health: The Environment Around the Tendon
The way your body processes and stores energy can have a significant effect on tendon health.
When blood sugar, cholesterol, or other metabolic markers remain elevated over time, they may influence the structure and function of tendon tissue.
Blood Sugar and Collagen
Persistently elevated blood sugar can cause sugar molecules to attach to collagen fibres through a process known as glycation.
Over time, this can make collagen stiffer and less adaptable. A tendon that is less flexible may not absorb, store, and release force as efficiently as it once did.
This does not mean that everyone with blood sugar concerns will develop tendon pain. It does mean that metabolic health can affect how well a tendon tolerates loading and how quickly it recovers.
Cholesterol and Tendon Structure
Elevated cholesterol may also influence tendon health.
Small cholesterol deposits can accumulate within tendon tissue and interfere with its normal organization. This may make the tendon more vulnerable to irritation, reduced capacity, and repeated flare-ups.
For someone with persistent or recurring tendon problems, looking at overall metabolic health may provide useful information that exercise alone cannot explain.
3. Hormonal Changes
Hormones act as internal messengers. They influence how tissues repair, adapt, and respond to physical stress.
For women, oestrogen appears to play an important role in maintaining the structure and mechanical properties of connective tissues, including tendons.
During perimenopause and menopause, oestrogen levels begin to fluctuate and eventually decline. These changes may affect how tendons respond to exercise, recover from loading, and maintain their strength and elasticity.
If tendon or joint symptoms appear during this stage of life, it does not necessarily mean that your technique is poor or that you have suddenly become fragile.
Your body may simply be adapting to a different hormonal environment.
This may require changes in training volume, recovery time, strength programming, and the rate at which activity is progressed.
4. Medications and Tendon Health
Sometimes the missing piece is not what you are doing, but what you are taking.
Certain medications are associated with an increased risk of tendon irritation or injury.
One important example is a class of antibiotics known as fluoroquinolones. These medications may sometimes be prescribed for respiratory, urinary, or other bacterial infections.
In some people, fluoroquinolones can interfere with the normal maintenance of tendon tissue and increase the risk of tendon pain or injury.
Other medications and medical treatments may also influence connective tissue, recovery, or physical capacity.
If you develop sudden tendon pain during or shortly after beginning a medication, speak with your physician or pharmacist. Do not stop taking a prescribed medication without medical guidance.
Connecting the Dots
Recurring tendon pain does not mean that your body is broken.
It also does not mean that you need to give up the activities, sports, work, or hobbies you enjoy.
It may simply mean that your tendon problem needs to be understood within a wider context.
A successful tendon recovery plan usually involves more than rest, ice, massage, braces, or a few isolated exercises.
It may include:
- Gradually rebuilding tendon strength and physical capacity
- Adjusting activity and training loads
- Improving sleep and recovery
- Managing stress
- Supporting metabolic health
- Eating enough protein and nutrient-rich food
- Considering hormonal changes
- Reviewing medications and overall health with an appropriate healthcare professional
- Tracking how the tendon responds over time
The goal is not simply to calm the pain temporarily.
The goal is to build a tendon that is stronger, more capable, and better prepared for the demands of your life.
Looking Beyond the Pain
When a tendon problem continues to return, it can be tempting to keep chasing the painful area with more treatments, more stretching, or more rest.
Sometimes the better question is:
What might be affecting this tendon’s ability to adapt, recover, and become stronger?
By looking at the whole person, not just the painful tendon, we can create a clearer and more effective path forward.
If you are tired of chasing symptoms and want to develop a personalized, capacity-building recovery strategy, we can look at the bigger picture together during your next visit.
