Shoulder Pain in Athletes and Active Individuals: What You Need to Know
The shoulder is the most mobile joint in the body — and that mobility comes with a trade-off. It is also one of the most frequently injured joints in athletic populations, and one of the most mismanaged.
Shoulder pain is not a diagnosis. “Impingement,” “rotator cuff tendinitis,” “bursitis” — these are descriptions of what’s happening in the joint, not explanations of why. And when you’re an athlete who needs to get back to training, understanding why matters.
At St. Louis Sports Clinic, we assess shoulder injuries the way sports medicine teams do: systematically, comprehensively, and with an eye on returning you to full function.
Common Shoulder Conditions in Athletes
Shoulder Impingement Syndrome
Impingement describes the mechanical pinching of soft tissue structures — typically the supraspinatus tendon and/or the subacromial bursa — between the humeral head and the acromion. It presents as pain with overhead reaching, throwing, pressing, or lifting. In most cases, impingement is driven by altered shoulder mechanics and muscular imbalances — not a fixed structural problem — which is why conservative care works well.
Rotator Cuff Tendinopathy and Tears
The rotator cuff is made up of four muscles (supraspinatus, infraspinatus, teres minor, subscapularis) that stabilize the humeral head in the glenoid. Tendinopathy — degenerative change in the tendon — is extremely common in overhead athletes and recreational weightlifters. Partial tears may be managed conservatively; full-thickness tears require assessment to determine whether surgery is warranted. We can help you understand your imaging and your options.
Labral Tears (SLAP and Bankart Lesions)
The labrum deepens the shoulder socket and anchors the biceps tendon. SLAP tears (superior labrum, anterior to posterior) are common in overhead athletes — throwers, swimmers, CrossFit athletes. Bankart lesions result from shoulder dislocations. Some labral tears are managed conservatively; others require surgical repair. Accurate diagnosis is critical, and Dr. Jessica Billham (DC, DACBR, RMSK) can interpret existing MRI or provide ultrasound imaging to guide clinical decision-making.
AC Joint Sprains
The acromioclavicular joint is frequently sprained in contact sports and fall-related mechanisms. Grade I and II sprains are managed conservatively and respond well to care. Grade III and above require orthopedic assessment.
Biceps Tendinopathy and Tears
Long head of biceps tendinopathy presents as anterior shoulder pain — common in throwing athletes, gymnasts, and weightlifters. Dry needling, shockwave therapy, and targeted loading are all effective tools.
Frozen Shoulder (Adhesive Capsulitis)
True frozen shoulder — with capsular fibrosis and progressive loss of all shoulder planes of motion — is more common in middle-aged adults with diabetes or thyroid conditions. It requires a different approach than mechanical shoulder injuries, and we’ve helped many patients through this frustrating condition.
Why Athletes Often Get the Wrong Care for Shoulder Pain
The most common pattern we see: an athlete develops shoulder pain, is told to rest, takes anti-inflammatories, maybe gets a cortisone injection, and is sent to PT for generic rotator cuff exercises. It works for a while, the athlete goes back to training, and the pain comes back — because the underlying mechanics were never fixed.
The problem isn’t the pain. The pain is a signal. The problem is why the shoulder is moving wrong.
Our assessment looks at:
- Thoracic mobility — Restricted thoracic rotation and extension are the most underdiagnosed contributors to shoulder impingement and overhead pain. If your T-spine can’t rotate, your shoulder compensates. That compensation causes impingement.
- Scapular mechanics — How your scapula moves during shoulder elevation matters enormously. Dyskinesis — abnormal scapular motion — is present in most athletes with shoulder impingement.
- Rotator cuff activation and strength — Particularly the lower trapezius, serratus anterior, and external rotators.
- Glenohumeral mobility — Internal rotation deficits (GIRD) are common in overhead athletes and contribute to impingement and posterior capsule tightness.
How We Treat Shoulder Pain at St. Louis Sports Clinic
Dry Needling: Trigger points in the upper trap, pec minor, infraspinatus, teres major, and subscapularis are extremely common contributors to shoulder pain. We dry needle the specific muscles driving dysfunction.
Shockwave Therapy: For calcific tendinitis of the shoulder, shockwave has strong evidence for breaking down calcium deposits and resolving pain in cases that have been refractory to other treatment. We also use it for chronic rotator cuff tendinopathy.
Soft Tissue Therapy & ART: Posterior capsule tightness, pec minor shortening, and posterior rotator cuff restrictions all respond well to ART and instrument-assisted soft tissue techniques.
Chiropractic Manipulation: Restricted AC joint, SC joint, glenohumeral joint, and T-spine mobility all contribute to shoulder dysfunction. Joint mobilization and manipulation restore movement and reduce the mechanical stress on the shoulder.
Progressive Rehabilitation: Scapular stabilization, rotator cuff loading, and sport-specific return-to-function programming. We don’t just treat the acute pain — we rebuild the mechanics.
Diagnostic Imaging: If you have existing X-ray or MRI and want a clinical interpretation, or if you need musculoskeletal ultrasound to assess the rotator cuff in real-time, Dr. Jessica Billham (DC, DACBR, RMSK) provides in-house imaging services.
Avoiding Shoulder Surgery — When Is It Possible?
Most cases of shoulder impingement, rotator cuff tendinopathy, and even partial tears can be managed successfully without surgery. Full-thickness rotator cuff tears in active individuals, unstable labral tears, and AC joint separations above Grade III typically require orthopedic evaluation.
We give you an honest assessment of what conservative care can realistically achieve. If we see you and believe you need to see an orthopedic surgeon, we’ll tell you — and we’ll refer you to one. We are not in the business of keeping patients in care that isn’t appropriate for their condition.
