Shoulder Overuse Injuries in Throwing and Racket Sports
In a Nutshell: Baseball, softball, tennis, pickleball, volleyball. Any sport with a repetitive overhead motion puts real demand on the shoulder, and overuse injuries here are extremely common.
Pickleball has exploded, tennis leagues are packed, and youth throwing sports keep kids busy nearly year-round now. All of that repetitive overhead motion adds up, and shoulders are paying the price.
Why Overhead Sports Are So Hard on Shoulders
The shoulder is built for mobility, which is exactly what makes it more vulnerable to overuse injury than a more stable joint like the hip. Every serve, throw, or overhead swing places repetitive stress on the same small group of muscles and tendons, particularly the rotator cuff, without much built-in structural support to share that load.
What We're Seeing Most Often
Rotator cuff tendinopathy, that dull, nagging ache with overhead movement, tops the list. We're also seeing a lot of shoulder impingement, where structures in the shoulder get pinched during overhead motion, often related to posture and shoulder blade mechanics rather than the shoulder joint itself. Labral irritation shows up too, especially in athletes with a high volume of throwing or serving.
The Role of the Shoulder Blade
Here's something a lot of people don't expect. A huge percentage of shoulder overuse issues actually trace back to how well the shoulder blade moves, not just the shoulder joint itself. If the shoulder blade isn't rotating and stabilizing properly during an overhead motion, the shoulder joint ends up compensating, and that compensation is often where the pain actually starts.
What Actually Helps
Addressing shoulder overuse injuries usually means looking well beyond just the sore spot. Shoulder blade mechanics, thoracic spine mobility, and rotator cuff strength all play a role, alongside managing the actual training or play volume that's driving the overuse in the first place.
Simply resting and hoping it goes away tends to provide temporary relief at best, since the underlying mechanical issue is usually still there once you go back to swinging or throwing.
The Bottom Line
If you've got that nagging shoulder ache that flares every time you play, it's worth getting an actual assessment rather than just pushing through it. Overhead sports aren't going anywhere, and neither should you.
FAQs
Why does my shoulder only hurt when I serve or throw, not during regular activities? This is a classic sign of an overuse pattern tied to the repetitive, sport-specific motion rather than a general shoulder problem, which is why it often doesn't show up during everyday movement.
Is rotator cuff pain always serious? Not necessarily. Rotator cuff tendinopathy exists on a spectrum, and many cases respond well to addressing the underlying mechanics and load management without more invasive intervention.
Can pickleball really cause the same injuries as tennis? Yes, the repetitive overhead and rotational demands are quite similar, and we're seeing a real increase in these overuse patterns as pickleball has grown in popularity.
Do I need to stop playing entirely if my shoulder hurts? Not always. In many cases, modifying volume or technique while addressing the underlying mechanical issue allows you to keep playing while you recover.
