Tendinitis is new or sudden swelling and irritation, called inflammation, of a tendon. Tendons are thick fibrous cords that attach muscle to bone. Tendinitis causes pain and tenderness just outside a joint.
Tendinitis can happen in any tendon. It's common around shoulders, elbows, wrists, hips, knees and heels. Tendinitis is sometimes called tendinopathy. Tendinopathy is an umbrella term for conditions affecting the tendon.
Most tendinitis can be treated with rest, physical therapy and medicine to reduce pain. Long-lasting tendon inflammation can cause a tendon to tear. A torn tendon might need surgery.
There are many types of tendinitis. Common types include:
Achilles tendinitis. The Achilles tendon is the band of tissue that connects calf muscles at the back of the lower leg to your heel bone. Achilles tendinitis is caused by overuse or strain on the Achilles tendon, such as when a runner increases the intensity of a running program.
Golfer's elbow. This condition, also known as medial epicondylitis, causes pain where the tendons of the forearm muscles attach to the bony bump on the inside of the elbow. The pain might spread into the forearm and wrist. It's not limited to golfers, but it is often caused by repeated rotation of the forearm and wrist.
Patellar tendinitis. This condition is an injury to the tendon connecting the kneecap, also called the patella, to the shinbone. Patellar tendinitis also is referred to as jumper's knee. The condition is most common in athletes whose sports involve frequent jumping, such as basketball and volleyball. But even people who don't take part in jumping sports can get patellar tendinitis.
Rotator cuff injury. The rotator cuff is a group of muscles and tendons that surround the shoulder joint. Rotator cuff injuries are most often caused by wear and tear of the tendon tissue over time due to repeated overhead motions or heavy lifting. These injuries are common in people with jobs such as carpentry or in people who play sports such as baseball or tennis. A rotator cuff injury can cause a dull ache in the shoulder that worsens at night or with reaching.
Tennis elbow. Pain from tennis elbow, also known as lateral epicondylitis, can be caused by overuse of the muscles and tendons in the elbow. It's often linked to repeated motions of the wrist and arm, for example, the motions used in tennis and other similar sports.
Symptoms of tendinitis tend to occur where a tendon attaches to a bone. Symptoms often include:
Most cases of tendinitis respond 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.
Tendinitis can be caused by a single overuse activity. But repeating the same movement over time is a more likely cause. Some people develop tendinitis because their jobs or hobbies involve motions that 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. In many cases tendinitis develops without a clear cause.
How you move when doing your sport or activity can affect your risk of developing tendinitis. Moving incorrectly can overload the tendon. Having proper form and technique is especially important when sports or a job requires repeated movements.
Risk factors for developing tendinitis include older age and having jobs that involve doing the same motion over and over. Some medical conditions and certain medicines also may increase the risk.
As people get older, their tendons become less flexible, making the tendons easier to injure. Tendons also are often slower to heal and recover from activity as people age.
Tendinitis is more common in people, such as gardeners and manual laborers, whose jobs involve:
When doing physical activities, the following can increase the risk of tendinitis:
If you have certain medical conditions, such as diabetes, or take certain medicines, you can have an increased risk of tendinitis. Medicines that may increase risk include:
Without treatment, tendinitis can increase the risk of a tendon breaking down or tearing. A completely torn tendon might need surgery.
To lower your chance of developing tendinitis, follow these suggestions:
Often, a physical exam alone can diagnose tendinitis. Your healthcare professional may press on the affected joint and move the joint into different positions.
Sometimes your healthcare professional may use imaging tests to help with diagnosis. Imaging tests may include:
The goals of tendinitis treatment are to relieve pain, reduce irritation and prevent future tendon conditions. Self-care, including rest, ice and pain relievers, might be all that's needed. But full recovery might take several months.
Changing how you do certain activities and doing physical therapy exercises can help improve pain and prevent future injuries. Other treatment options include noninvasive and surgical procedures.
Treatment options for tendinitis may include:
Pain relievers, such as aspirin, naproxen sodium (Aleve), ibuprofen (Advil, Motrin IB, others) or acetaminophen (Tylenol, others) may lessen pain. You also can apply pain-relieving creams or gels to the skin.
Physical therapy exercises can help strengthen the muscle and tendon in the affected area. You can do resistance exercises to effectively treat many long-lasting tendon conditions.
In situations where physical therapy hasn't resolved symptoms, your healthcare professional might suggest:
To treat tendinitis at home, use rest, ice, compression and elevation. This treatment can help speed recovery and help prevent more issues.
Although rest is a key to treating tendinitis, not moving joints can cause them to become stiff. After a few days of resting the injured area, gently move it through its full range of motion to keep your joints flexible.
You might start by talking to your family healthcare professional. You may be referred to a specialist in sports medicine or physical medicine and rehabilitation.
