Tendinitis Overview

Who gets tendinitis?

Anyone can get tendinitis. However, it's more common in those who do repetitive activities. Some of these activities include:

  • Gardening/landscaping
  • Carpentry
  • Shoveling
  • Painting
  • Scrubbing
  • Tennis, golf, skiing, baseball (throwing and pitching)

Other risk factors for tendinitis include:

  • Poor posture at work or home.
  • Presence of certain diseases: rheumatoid arthritis, gout/pseudogout, blood or kidney diseases. These diseases can weaken muscles.
  • Adults 40 years of age and older. As tendons age, they tolerate less stress, are less elastic, and tear more easily.
  • Medications (rare occurrence): fluoroquinolone antibiotics (such as ciprofloxacin [Cipro®] and norfloxacin [Noroxin®]) and statins (drugs that lower cholesterol). These medicines can cause tendons to tear.

Where does tendinitis occur?

Tendinitis can occur in almost any area of the body where a tendon connects a bone to a muscle. The most common places are:

  • Base of the thumb
  • Elbow
  • Shoulder
  • Hip
  • Knee
  • Achilles tendon (connects the calf muscles to the heel bone)

What causes tendinitis?

Tendinitis most often is caused by repetitive, minor impact on the affected area, or from a sudden, more serious injury.

What are the symptoms of tendinitis?

  • Pain at the site of the tendon and surrounding area. Pain may be a gradual buildup or sudden and severe, especially if calcium deposits are present.
  • Loss of motion in the shoulder, called adhesive capsulitis or “frozen shoulder”.
