What is Tendonitis?

Tendonitis is a condition where a tendon becomes irritated or inflamed. This condition often develops when a tendon is overworked, especially with repeated motions over time. It can affect many areas of the body, including the shoulders, elbows, knees, and ankles.

It can happen during sports, exercise, or even daily tasks like typing or lifting. Other factors that may increase risk include:

• Sudden increases in activity level
• Improper form during exercise
• Aging, which can make tendons less flexible
• Certain health conditions affecting joints

Symptoms

Tendonitis usually develops gradually and may worsen with continued activity. Common signs include:

• Pain near a joint, especially with movement
• Tenderness when touching the area
• Swelling or mild warmth
• Stiffness or limited motion
• Weakness in the affected limb

How is it diagnosed?

Your provider will begin by discussing your symptoms, daily activities, and any recent injuries. A physical exam helps identify areas of pain, swelling, and limited range of motion.

If more information is needed, imaging tests such as an ultrasound or MRI may be used to look at the tendon. X-rays may also be done to rule out bone-related problems. In rare cases, lab tests are used if an infection is a concern.

How is it treated?

Treatment usually starts with simple steps to reduce strain and allow healing. These may include rest, ice, and over-the-counter medications to ease pain and swelling.

As symptoms improve, physical therapy can help restore strength and flexibility. Some people may benefit from supportive braces or targeted injections for temporary relief.

Surgery is rarely needed and is typically only considered if the tendon is severely damaged or torn.

Most people recover well with early care and gradual return to activity.
