Shoulder Pain From Tennis, Pickleball, or Padel? It's Rarely Just the Rotator Cuff.

You feel it on your serve. Or reaching back for an overhead smash. Or just generally aching after a match that never used to bother you. Shoulder pain from racket sports is one of the most common injuries we see at MVMNT Rehab — and one of the most misunderstood.

Most players assume it's the rotator cuff, ice it, rest a few days, and get back out there. Sometimes that's enough. Often it isn't — and the pain becomes a recurring part of playing the sport you love.

Here's what's actually going on, and why the standard advice usually falls short.

Why Racket Sports Are So Hard on the Shoulder

Every overhead swing — a tennis serve, a pickleball smash, a padel bandeja — asks your shoulder to do something it wasn't built to do casually: move through a large range of motion, at high speed, repeatedly, while generating and absorbing significant force.

The shoulder is the most mobile joint in the body, which means it relies heavily on muscles, tendons, and coordinated movement patterns for stability — unlike the hip, which gets more of its stability from bony structure. That mobility is exactly what makes the shoulder so vulnerable to overuse injuries in racket sports.

The rotator cuff — four muscles that stabilize the ball-and-socket joint — takes on a huge amount of that load. So it's often where pain shows up first. But it's not always where the problem starts.

The Injuries We See Most Often

Rotator Cuff Tendinopathy

This is the most common shoulder issue in racket sport players. Repeated overhead loading — serves, smashes, overheads — irritates the rotator cuff tendons, particularly the supraspinatus. Early on, this shows up as an ache during or after play. Left unaddressed, it can progress to pain during everyday activities like reaching overhead or sleeping on that side.

Shoulder Impingement

This happens when the space between the top of the humerus and the acromion (part of the shoulder blade) narrows, causing the rotator cuff tendons or the bursa to get pinched during overhead motion. It's common in players with poor scapular control or restricted thoracic mobility, because both of those issues change how much space is actually available during an overhead swing.

Labral Irritation

The labrum is the cartilage rim that helps stabilize the ball-and-socket joint. Repetitive overhead loading — especially the deceleration phase after a serve or overhead — can irritate or, in more significant cases, tear the labrum. This tends to show up as deeper, more central shoulder pain, sometimes with clicking or a sense of instability.

Biceps Tendon Irritation

The long head of the biceps tendon runs directly through the front of the shoulder joint and attaches near the labrum. It's frequently involved alongside rotator cuff or labral issues, and can cause pain at the front of the shoulder that's easy to misattribute to the rotator cuff alone.

Why the Rotator Cuff Isn't the Whole Story

Here's what most treatment for racket sport shoulder pain misses: the rotator cuff doesn't work in isolation. It's the last link in a kinetic chain that starts at the ground and moves up through the hips, core, thoracic spine, and shoulder blade before it ever reaches the arm.

Scapular Control

Your shoulder blade is supposed to move in a coordinated pattern with your arm during every overhead motion — this is called scapulohumeral rhythm. When the muscles that control the shoulder blade (particularly the serratus anterior and lower trapezius) are weak or poorly coordinated, the shoulder blade doesn't position itself correctly during the swing. This directly narrows the space available for the rotator cuff tendons, increasing the risk of impingement with every serve or overhead.

This is one of the most common findings we see in players with recurring shoulder pain, and it's rarely addressed by rest or ice alone.

Thoracic Spine Mobility

Your mid-back needs to extend and rotate freely for a proper overhead swing. When the thoracic spine is stiff — which is extremely common in adults who sit for part of the day — the shoulder has to compensate by moving into a greater range than it's designed to handle safely. Over time, that excess demand on the shoulder is a direct contributor to rotator cuff and labral irritation.

Hip and Core Involvement

This surprises a lot of players, but it matters more than most people realize. Power in a tennis serve or a padel smash is generated from the ground up — through the legs, hips, and core — and transferred through the trunk into the arm. When that kinetic chain breaks down (weak hips, poor rotational core control), the shoulder ends up generating more of the force on its own, which it isn't built to sustain over hundreds of repetitions per match.

Players who "arm" their serves or overheads — relying on the shoulder to generate power instead of the legs and trunk — are significantly more prone to overuse injuries.

What Actually Works: The MVMNT Rehab Approach

At MVMNT Rehab in Alpharetta, we treat a lot of racket sport players — tennis, pickleball, and padel are everywhere in this area, and shoulder pain is one of the most common reasons players come see us.

Our approach looks at the whole kinetic chain, not just the shoulder joint:

Full Movement Assessment

We evaluate your shoulder mobility, scapular control, thoracic spine mobility, and how well your hips and core are contributing to your swing mechanics. This tells us whether the shoulder itself is the primary problem, or whether it's compensating for a restriction or weakness elsewhere in the chain.

Active Release Technique (ART)

ART is highly effective for the soft tissue restrictions that build up in the rotator cuff, biceps tendon, and surrounding shoulder musculature from repetitive overhead loading. We work through the affected tissue while you move through specific ranges of motion, breaking up adhesions and restoring normal tissue glide.

Graston Technique

For chronic tendinopathy that's developed scar tissue and fascial restriction, Graston's instrument-assisted approach gets into the deeper tissue layers to stimulate healing in areas that haven't been responding to rest alone.

Joint Mobilization

If the thoracic spine or the shoulder joint itself has lost mobility, we restore it directly. Improving thoracic extension and rotation is often one of the fastest ways to reduce the compensatory load being placed on the shoulder during overhead motion.

Scapular and Rotator Cuff Strengthening

We build progressive strength and control work specifically targeting the muscles responsible for scapular positioning and rotator cuff stability — the foundation that has to be in place for the shoulder to tolerate repetitive overhead loading without breaking down.

Kinetic Chain Retraining

For players whose mechanics are putting excess load on the shoulder, we work on hip and core engagement so more of the power in your swing is coming from the ground up — taking demand off the shoulder itself.

Signs You Shouldn't Keep Playing Through It

• Shoulder pain that shows up consistently during serves or overheads

• Pain that lingers into the next day rather than settling down quickly

• Reaching overhead in everyday life (getting something off a shelf) has started to hurt

• Clicking, popping, or a sense of instability in the shoulder

• Weakness that's affecting the power or consistency of your shots

• You've had this more than 4–6 weeks with no real improvement

The longer overhead athletes play through shoulder pain, the more likely a manageable tendon irritation becomes a more significant issue. Catching it early makes a real difference in how quickly — and how completely — it resolves.
