Tendonitis Q & A

What is tendonitis?

Tendonitis is inflammation or irritation of a tendon. Tendons are tough fibrous tissues that attach muscle to bone and support mobility. 

Tendonitis most often occurs from overuse but can also develop after an acute injury. 

What are the symptoms of tendonitis?

Pain at the site of your inflamed tendon is the most common symptom of tendonitis. The pain may develop gradually or occur suddenly. The discomfort may range from a dull ache to severe pain.

Calcific tendonitis occurs when you have a buildup of hard calcium deposits in the tendon. This type of tendonitis causes severe pain and most often affects the tendons in the shoulder.

What are the types of tendonitis?

Tendonitis may affect any tendon that connects muscle to bone. Dr. Westerdahl treats many types of tendonitis that affect the mobile joints athletes and active individuals use when playing their sport.

Types of tendonitis include:

  • Patella tendonitis (knee pain)
  • Shoulder tendonitis
  • Gluteus medius tendonitis (hip pain)
  • Tennis elbow
  • Golfer’s elbow
  • Achilles Tendonitis
  • Hand and wrist tendinopathy


Tendonitis may be acute or chronic. Dr. Westerdahl uses the term tendinopathy for patients with chronic tendon problems. 

How is tendonitis treated?

Dr. Westerdahl takes a conservative approach to care, using many innovative nonsurgical treatments for tendonitis. He customizes your treatment plan based on the location of your tendonitis, the severity of your symptoms, and your usual level of activity.

Initially, he may recommend:

  • Rest, ice, compression, and elevation (RICE)
  • Activity modification
  • Nonsteroidal anti-inflammatory drugs (NSAIDs)
  • Physical therapy
  • Bracing or splinting


Sports Health Northwest, Inc, also offers minimally invasive treatments for tendonitis, including:

Percutaneous tenotomy

For chronic tendonitis, Dr. Westerdahl may recommend percutaneous tenotomy. During this minimally invasive procedure, he uses advanced tools and technology to remove the damaged tissue without harming the healthy tissue. 

Ultrasound-guided calcific tendonitis lavage

For calcific tendonitis, Dr. Westerdahl performs an ultrasound-guided lavage. During the needle-based procedure, he uses fluid to flush out the calcium deposits from the affected tendon. 

The minimally invasive procedure requires little downtime and allows patients to quickly get back to their active lifestyle.

Tendonitis is a common condition in people who engage in repetitive movements. For expert care of your tendonitis from an experienced sports medicine physician, call Sports Health Northwest, Inc, or schedule an appointment online today.
