Tendonitis is often referred to as inflammation of the tendons, ie those structures that join muscles and bones.

In reality it is a wrong definition because the inflammation, in general, involves the increase of the blood supply to a tissue, which instead does not happen in the tendons.

Therefore one should speak of peritendinitis, since the real inflamed part is that which covers the tendon.

Nervenia associates with the classic cures of tendinitis, deep nerve stimulation (DNS). This approach is based on the fact that tendons can easily handle work overloads when they are perfectly innervated and nourished, and this is given only by a perfectly functioning tendon nerve.


We can say that in addition to work overload, due to sports, micro-traumatic or postural factors, tendinitis almost always depends on nerve suffering: its ability to transmit signals that regulate the metabolic and histological activities of the tendon is altered. So the tendon in a certain sense cannot regenerate at the speed required by the overload, it starts to get irritated and then degenerate into tendonitis and then into tendinosis.


Tendonitis is a very common disease. Generally it causes pain that is felt at the beginning of an activity, such as walking, a job or a sporting activity. Then these pains tend to improve over the course of the activity itself, so that patients often describe the problem as “an annoying pain that disappears when I warm up”. Very often tendinitis develops into tendinosis and the clinical picture becomes more complicated. The pain decreases until it disappears, but the tendon begins to progressively degenerate:

  • becomes increasingly thick and deformed,
  • fibrous nodules are formed (such as in the Achilles tendon) which alter the capacity of resistance to effort and which lead to the sudden rupture of the tendon,
  • calcifications are formed (for example in the rotator cuff, with the appearance of articular noises during movements).


The diagnosis of tendinitis is purely clinical on the history reported by the patient, but can be easily investigated with an ultrasound or magnetic resonance imaging (MRI).

Cures and remedies

Even well-cured tendinitis with traditional methods can unfortunately result in tendinosis. This is why we at Nervenia include the evaluation of nerve transmission capacity in the treatment of tendinitis and the treatment of nerves with neuromodulation. This is essential to find the solution to the problem and to avoid relapses or deterioration.

If tendinosis is already present, to contain progressive degeneration, it is essential to restore nerve function as best as possible through a deep nerve stimulation protocol (DNS), a particular type of current that improves the functionality of the peripheral nervous system. in order to improve metabolic and histological controls on tendon tissue.
