Tendinopathy (Tendon Injuries)

Tendinopathy, more commonly called as tendinitis, is the inflammation of the tendon, a fibrous structure that connects muscle to bone. Tendinopathy commonly occurs due to gradual wear and tear of the tendon from overuse or aging. In addition to pain, tendinopathy also cause stiffness and loss of strength in the affected area.

Typically, tendon injuries occur in three areas:

  • Musculotendinous junction (where the tendon joins the muscle)
  • Mid-tendon (non-insertional tendinopathy)
  • Tendon insertion


Diabetics, post-menopausal women, and men with high central adiposity (body fat) are the most at risk to develop tendinopathies.


Tendinopathy usually causes pain, stiffness, and weakness in the affected area. The symptoms of a tendon injury are very similar to those of bursitis.

  • Tenderness, redness, warmth, or swollen if there is inflammation.
  • The pain worsens when you use the tendon.
  • A crunchy sound or feeling when you use the tendon.
  • More pain and stiffness during the night or getting up in the morning.

Tendinitis (or Tendonitis)

This means “inflammation of the tendon.” It is a condition in which the tissue connecting muscle to bone becomes inflamed. Tendonitis is most common in the shoulder, elbow, knee, wrist, and heel, although it can happen anywhere that tendons are found in the body. For uncertain reasons, tendonitis is common in people with diabetes. Symptoms include pain at the site of the tendon and surrounding area. It can gradually increase or be sudden and severe, especially if calcium deposits are present. Patients also experience loss of motion in the shoulder, called “adhesive capsulitis” or frozen shoulder.

Anyone can get tendinitis, but it is more common in adults, especially those over 40. As tendons age, they tolerate less stress, are less elastic, and are easier to tear.
