Tendinitis: shoulder, elbow, heel — treatment in Luxembourg

Tendinitis is inflammation or irritation of a tendon, the fibrous cord that connects muscle to bone. It usually follows repeated or excessive strain: a repetitive work movement at the elbow or wrist, a shoulder motion in racquet sports or swimming, repeated heel impact in runners. The pain sits precisely along the tendon and worsens with effort or pressure on the area. In Luxembourg, most cases are managed by a general practitioner or a sports medicine doctor, with a rheumatologist or orthopaedic surgeon stepping in when needed.

An overworked tendon, not a broken one

Unlike muscle, a tendon heals slowly because it receives little blood supply. When load repeatedly exceeds its capacity to recover, tiny injuries build up faster than they can repair — that is essentially what tendinitis is. It tends to appear in predictable spots depending on the activity: the shoulder in overhead jobs or throwing sports, the elbow in tennis players or manual trades (“tennis elbow”, “golfer’s elbow”), the Achilles tendon at the heel in runners.

Relative rest, not total shutdown

The most common mistake is assuming the joint must be fully immobilised. In reality, stopping all movement weakens the tendon and slows healing almost as much as pushing through the pain does. The right approach is relative rest: reducing or adapting the activity that triggers the pain while keeping gentle mobility in the joint. Ice, short courses of anti-inflammatories discussed with a doctor, and above all specific exercises guided by a physiotherapist form the backbone of treatment. These exercises, known as eccentric loading, apply controlled, progressive strain to the tendon — it is precisely this well-dosed loading, not complete rest, that stimulates repair.

Returning to activity, one step at a time

Rushing back into the activity that caused the tendinitis is the most frequent cause of relapse. Gradual progression is the rule: increasing intensity, duration or frequency in small steps, watching that pain does not return the next day. A flawed sporting or work technique, or unsuitable equipment (shoes, racquet, workstation) often deserves a review too, or the tendinitis is likely to come straight back once activity resumes.

When to seek care, and what imaging can add

Mild discomfort that improves with relative rest and a few weeks of adjustment usually needs no imaging. A consultation makes sense if pain persists despite these measures, becomes intense or interferes with daily tasks, or if a sudden sharp pain with a “snapping” sensation suggests a tendon tear. Ultrasound or MRI, ordered by a doctor, can then clarify the state of the tendon.

Who to see in Luxembourg

A general practitioner or a sports medicine doctor manages the vast majority of tendinitis cases, supported by physiotherapy. A rheumatologist becomes involved when the diagnosis stays unclear or for certain procedures such as a targeted injection. An orthopaedic surgeon is called upon when tendinitis resists several months of well-conducted treatment, or when a tendon rupture is confirmed.

Care pathway and CNS coverage in Luxembourg

In Luxembourg, medical consultations, prescribed imaging and physiotherapy sessions are covered by the Caisse nationale de santé according to the rules in force, detailed on cns.lu. The general practitioner or sports medicine doctor remains the natural entry point before any specialist referral.

Preventing recurrence

Once pain has settled, a few habits reduce the chance of tendinitis returning: proper warm-up before exertion, gradual increases in training load or volume, attention to equipment and workstation ergonomics, and regular stretching of the affected tendon. Well-treated tendinitis heals in the vast majority of cases; it is often rushing the comeback that turns a single episode into a chronic problem.

Tendinitis or another kind of joint pain?

Tendinitis is often confused with joint pain of another origin, such as bursitis or a problem with the joint itself. The difference mainly comes down to the precise location of the pain: tendinitis hurts exactly along the tendon’s path and when that specific muscle is moved against resistance, while a joint problem tends to spread more broadly and limits all movement of the joint, including passive movement. This distinction, which a doctor establishes through a targeted exam, directly guides treatment and avoids chasing the wrong target.

When tendinitis becomes chronic

Some cases of tendinitis, poorly treated or restarted too early on several occasions, evolve into a chronic form called tendinopathy, where the initial inflammation gives way to gradual degeneration of the tendon tissue. The tendon then becomes more fragile, less elastic, and the pain, often duller, settles in over the long term. This evolution is a good reason not to dismiss a first episode of tendinitis: the earlier and better managed the treatment, the higher the chances of a full recovery.
