Tendons connect muscle to bone and help move joints. Tendinopathy is an injury to the tendon. These injuries tend to occur in tendons near joints such as knee, shoulder, and ankle. The injuries can include:

• Tendinitis—An inflammation of the tendon. Although this term is used often, most cases of tendinopathy are not associated with significant inflammation.
• Tendinosis—Microtears in the tendon tissue with no significant inflammation.

The following tendons are often involved:

• Wrist extensors near the elbow, on the outside
• Wrist flexors near the elbow, on the inside

Tendinopathy and the associated pain may take months to resolve. You may need medication for pain relief.

• Overuse can be the result of doing any activity too much
• Strenuous or repetitive activities
  • Sports
  • Physical labor
  • Housework
• Physical problems
  • Muscle imbalance
  • Decreased flexibility
  • Overweight
  • Advancing age

• Pain in the tendon or surrounding area, particularly with activity
• Decreased motion of related joints
• Local swelling
• Weakness

• X-ray
• MRI scan
• Ultrasound

• Gradually work yourself into shape for a new activity.
• Gradually increase the length of time and intensity of activities.
• If you have a tendon that has been a problem, gradually stretch out that muscle/tendon unit.
• Strengthen the muscle to which the tendon is attached.
• If you have pain, do not ignore it. Early treatment can prevent the problem from becoming serious.
• Learn to back off from activities if you are tired or not used to the activity.
• Warm-up the affected area before activity.
