Tendinopathy

March 22, 2025

Overview

Tendinopathy is a term for any condition that affects a tendon. Tendons are cords that attach muscle to bone. Tendinopathy, which can cause pain and tenderness, is common. It is often caused by overuse or repeated movement and tends to affect certain tendons in the arm or leg.

Tendinopathy is an umbrella term for conditions affecting the tendon that include tendinitis, tendinosis and tenosynovitis:

  • Tendinitis is new or sudden swelling and irritation, called inflammation, of a tendon. Often, people mistakenly call all tendon conditions by this term.
  • Tendinosis is breakdown change in the tendon that occurs gradually over time.
  • Tenosynovitis is inflammation of a thin layer of tissue that surrounds a tendon, called the sheath.

Tendon conditions can occur in any tendon, but they are common in the shoulders, elbows, wrists, hips, knees and heels. Most tendinopathy can be treated with rest, physical therapy and medicine to reduce pain.

Tennis elbow

Tennis elbow

The pain of tennis elbow occurs mainly where the tough, cord-like tissues of forearm muscles, known as tendons, attach to a bony bump on the outside of the elbow. Tiny tears and longtime swelling, known as inflammation, can cause the tendon to break down. This causes the pain.

Symptoms

Tendinopathy symptoms can vary based on the type. Symptoms tend to occur where the tendon attaches to the bone and often include:

  • Pain, often described as a dull ache, especially when moving the hurt limb or joint.
  • Stiffness or weakness in the affected area.
  • Tenderness in the affected area.
  • Mild swelling.

When to see a doctor

You can treat many cases of tendinopathy with self-care measures, such as rest, ice and pain relievers. See your healthcare professional if your symptoms don't lessen after a few days and if they get in the way of daily activities.

Causes

Tendinopathy can be caused by wear and tear on a tendon. This can happen due to overuse or naturally over time as people age and their tendons become less flexible. Most people develop tendinopathy because their jobs or hobbies involve motions they repeat over and over. Jobs such as carpentry or house painting or sports such as baseball, tennis and golf require the same motions to be repeated. Over time, this puts stress on the tendons. Some tendinopathies also can be caused by sudden injury such as a fall or accident.

How you move when doing your sport or activity can affect your risk of developing tendinopathy. Moving incorrectly can overload the tendon. Having proper form and technique is especially important when having to repeat movements for sports or a job.

Risk factors

Risk factors for developing tendinopathy include older age and having jobs or hobbies that involve doing the same motion over and over. Some medical conditions and certain medicines also may increase the risk.

Age

As people get older, their tendons become less flexible, making the tendons easier to injure.

Work

Tendinopathy is more common in certain workers, such as gardeners, carpenters and painters, whose jobs involve:

  • Repeated motions, such as raking or swinging a hammer.
  • Overhead motions, such as reaching up.

Activities

When you're doing physical activities, the following can increase your risk of developing a tendinopathy:

  • Sudden increase in amount or difficulty of training.
  • Too little recovery time after an injury or too little time to get used to the activity again after time off.
  • Hard surfaces, such as concrete or gym floors.
  • Poor equipment, such as old shoes or ones without good support.
  • Poor posture or poor technique, such as incorrect form when playing tennis or throwing a ball.

Medical conditions and medicines

If you have certain medical conditions, such as diabetes, or take certain medicines, you can have an increased risk of tendinopathy. Medicines that may increase risk include:

  • Antibiotics known as fluoroquinolones.
  • Corticosteroids such as cortisone.
  • Statins, used to lower cholesterol levels.
  • Aromatase inhibitors, used to lower breast cancer risk.

Prevention

To lower your chance of developing a tendinopathy, follow these suggestions:

  • Ease up. Avoid activities that place too much stress on the tendons, especially for long periods. If you have pain during an exercise, stop and rest.
  • Mix it up. If one exercise or activity causes you pain, take a break from it and try something else. Cross-training can help you mix high-impact exercise, such as running, with low-impact exercise, such as biking or swimming.
  • Improve the way you move. If you don't do an activity or exercise properly, you could be setting yourself up for problems with the tendons. Think about taking lessons or getting professional instructions when starting a new sport or using exercise equipment.
  • Prepare your muscles. Strengthen muscles used in your activity or sport. For example, if you play baseball, use weights to strengthen the specific muscles you need to use. Strengthening muscles that you'll be using can help them bear the load better and lower the risk of injury.
