SymptomsandDiagnosis

Symptoms

Problems may be:

  • Pain in the shoulder
  • Pain with throwing motion
  • Shoulder may slip out of place
  • Shoulder or arm weakness
  • Shoulder may feel loose

Diagnosis

The doctor will ask about symptoms and past health. A physical exam will be done. It will focus on the shoulder.

Pictures of your shoulder may be taken. This can be done with x-rays or an MRI scan.

Treatments

Treatment

It may take 3 months to heal. The goals of treatment are to manage symptoms during that time. This may include:

  • Medicine to ease pain and swelling
  • A sling to prevent the shoulder from moving as it heals
  • Exercises to help with strength, flexibility, and range of motion

Surgery

Some people may need surgery when other methods do not help. It may be done to repair torn or stretched ligaments so they can hold the shoulder joint in place.

Prevention

Strengthening the rotator cuff muscles may help prevent some injuries. This can be done with exercise.
