Shoulder Anatomy

What causes rotator cuff tendinitis?

The tendon can become trapped by your arm bone when you lift your arm. Heavy lifting or throwing can cause overuse or an injury. This may happen if you play a sport such as baseball or tennis. A fall or other shoulder injury may also damage your rotator cuff. Calcium deposits may form in the tendons. This causes inflammation and swelling.

What are the signs and symptoms of rotator cuff tendinitis?

  • Pain and swelling in your shoulder, especially when you lift your arm over your head
  • Trouble moving your arm
  • Shoulder or arm weakness or stiffness
  • Pain that is worse after you sleep on the affected shoulder
  • Pain even when you are resting

How is rotator cuff tendinitis diagnosed?

Your healthcare provider may test your shoulder by moving your arm in different directions and raising it over your head. Tell your provider if you had a shoulder injury, and when it happened. An x-ray, ultrasound, or MRI may be used to check for tendon injuries or problems. You may be given contrast liquid to help the pictures show up better. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid. Do not enter the MRI room with any metal. Metal can cause serious injury. Tell the healthcare provider if you have any metal in or on your body.

How is rotator cuff tendinitis treated?

  • Medicines such as steroids or NSAIDs may be used to reduce swelling. This can help relieve pain. Steroids may be injected into the rotator cuff area. NSAIDs are available without a doctor's order. Ask your healthcare provider which medicine is right for you. Ask how much to take and when to take it. Take as directed. NSAIDs can cause stomach bleeding or kidney problems if not taken correctly.
  • Surgery may be needed if the pain and tightening in your shoulder do not go away. This may also be done if pain worsens or is so severe that it affects your daily activities. During surgery, your healthcare provider may remove bone spurs and inflamed tissue around the shoulder.
  • Physical therapy can help you improve movement and strength, and decrease pain. A physical therapist will teach you safe exercises. The exercises may help you move your shoulder normally again and strengthen your rotator cuff. You may learn changes to make to your daily activities that will help decrease stress on your tendons.

How can I care for my rotator cuff tendinitis at home?

  • Rest as directed. Limit activity on your affected shoulder to decrease stress on the tendon. This may help prevent further damage, decrease pain, and promote healing.
