Tennis Shoulder

Tennis shoulder is a popular term for shoulder pain caused by tennis and other racquet sports, not a single diagnosis. Repeated serving and overhead smashes put large forces on the shoulder, leading to rotator cuff tendinopathy, impingement, labral tears, loss of internal rotation and poor shoulder blade control. Pain is usually felt at the front or top of the shoulder during serves. Most players recover with rest from overhead strokes, targeted physical therapy and technique changes; surgery is rarely needed.

Also called: Tennis-related shoulder pain, racquet sport shoulder injury, thrower's shoulder, overhead athlete shoulder, tennis shoulder syndrome (dropped dominant shoulder)

At a glance

What it is
Overuse shoulder pain from racquet sports, mainly the serve and overhead.
Common causes
Rotator cuff tendinopathy, impingement, labral (SLAP) tears, loss of internal rotation (GIRD), scapular dyskinesis.
Symptoms
Pain serving or reaching overhead, a "dead arm", weakness, clicking, night pain.
Diagnosis
Sports medicine exam; ultrasound or MRI if not improving.
Treatment
Relative rest, physical therapy, stretching and strengthening, technique and equipment changes.
Prevention
Warm-up, rotator cuff and scapular strengthening, sleeper stretch, gradual load increases.

When to get help

Call 911 or go to the ER

  • Shoulder or arm pain with chest pressure, breathlessness or sweating: call 911 or your local emergency number

See a doctor within a day or two

  • A sudden pop with immediate weakness or inability to lift the arm
  • A shoulder that slips out of place or looks deformed
  • Numbness, tingling or coldness of the arm or hand, or a swollen, discolored arm (possible nerve or blood vessel compression)

Book a routine appointment

  • Shoulder pain during serves that persists for more than 2 weeks despite rest
  • Clicking, catching or a "dead arm" sensation with overhead strokes
  • Night pain or loss of serve speed or control

Usually safe to manage at home

  • Mild soreness after a long match or a new training load that settles within a few days

Why tennis stresses the shoulder

During the serve, the shoulder rotates extremely fast and must then decelerate the arm after contact. The rotator cuff, labrum and shoulder blade muscles absorb these forces thousands of times a season. Weakness, fatigue, stiffness or poor technique shifts load onto vulnerable structures.

Common causes of tennis shoulder

ConditionWhat happensTypical symptoms
Rotator cuff tendinopathyOverload of the cuff tendonsAche at the top or side of the shoulder with serves
ImpingementCuff tendons and bursa pinched under the acromion or inside the jointPain in the cocking phase of the serve, painful arc
Labral tear (SLAP)The rim of cartilage tears where the biceps attachesDeep pain, clicking, "dead arm", loss of velocity
Biceps tendinitisIrritation of the long head of bicepsPain at the front of the shoulder
GIRDTight back of the shoulder reduces internal rotationOften silent; increases risk of other injuries
Scapular dyskinesisPoor shoulder blade controlShoulder blade sticking out; fatigue; pain
InstabilitySubtle looseness from repetitive stressApprehension, clicking, pain at extremes

Older players are more likely to have degenerative cuff problems or tears; younger players more often have instability, labral injuries and GIRD.

A related pattern, sometimes also called "tennis shoulder", is a dropped dominant shoulder seen in long-time players, where the playing-side shoulder sits lower because of muscle development and laxity. It is usually painless.

Tennis shoulder vs tennis elbow

Tennis elbow is overuse of the forearm extensor tendons, causing pain on the outer elbow with backhands and gripping. Tennis shoulder affects the shoulder, mainly with serves and overheads. Players can have both, often linked by poor kinetic chain mechanics.

Diagnosis

A sports medicine doctor or physical therapist will:

  • ask about pain timing in the stroke, training load and changes in equipment
  • assess shoulder range of motion, comparing internal and external rotation between sides
  • test rotator cuff strength, scapular movement and labral signs
  • check the neck, core and legs, which contribute to serve mechanics
  • order ultrasound or MRI (often MR arthrogram for the labrum) if symptoms persist or a tear is suspected

Treatment

Load management

  • stop serving and overheads temporarily; groundstrokes may continue if pain-free
  • reduce practice volume, then return gradually

Physical therapy

  • Sleeper and cross-body stretches to restore internal rotation.
  • Rotator cuff strengthening with bands, especially external rotators.
  • Scapular stabilizer exercises: rows, wall slides, serratus punches.
  • Core and leg strengthening to share load through the kinetic chain.
  • Progressive return-to-serve program.

Pain relief

Ice after play and over-the-counter pain relievers in the short term. Follow the label dose, and avoid NSAIDs if you have kidney problems or stomach ulcers. A steroid injection may be considered for persistent bursitis or impingement but is used sparingly in athletes.

Technique and equipment

  • coaching to optimize serve mechanics, including leg drive and trunk rotation
  • appropriate racquet weight and grip size
  • lower string tension or softer strings

Surgery

Reserved for significant rotator cuff tears, symptomatic labral tears or instability that do not improve with several months of rehabilitation.

Prevention

  • dynamic warm-up before playing, including shoulder and trunk movements
  • year-round rotator cuff and scapular strengthening 2 to 3 times a week
  • daily sleeper stretch if internal rotation is limited
  • avoid sudden increases in serving volume or tournament load
  • adequate rest between matches

Frequently asked questions

What is tennis shoulder?

Tennis shoulder is a general term for shoulder pain caused by tennis, usually from overuse during serves and overheads. Common underlying problems include rotator cuff tendinopathy, impingement, labral tears and poor shoulder blade control.

Why does my shoulder hurt when I serve?

Serving places large forces on the rotator cuff and labrum. Pain often comes from tendon overload or impingement, especially if the shoulder is tight, the cuff or shoulder blade muscles are weak, or technique relies too much on the arm.

How long does tennis shoulder take to heal?

Mild tendinopathy often improves within 4 to 8 weeks with rest from serving and physical therapy. Labral tears or significant rotator cuff injuries can take several months, and longer if surgery is needed.

What exercises help tennis shoulder?

Sleeper stretches, cross-body stretches, external rotation strengthening with bands, rows and scapular stabilization exercises are common. A physical therapist can tailor a program and guide your return to serving.
