Shoulder Pain in Brentwood Bay: Causes, Treatment & When to See a Chiropractor

Shoulder pain is one of those injuries that has a way of creeping into everything. Whether it's reaching for something overhead, sleeping on your side, paddling out at Brentwood Bay, or simply lifting your kids — when your shoulder isn't working properly, you feel it constantly. The shoulder is the most mobile joint in the body, which is exactly what makes it so vulnerable to injury and so frustrating to treat when something goes wrong.

At Brentwood Chiropractic Group, shoulder pain is one of the most common presentations we see — and one of the most frequently mismanaged. Patients often come in after weeks of rest, ice, and anti-inflammatories that haven't resolved the problem, or after being told it's "just a strain" when the actual cause is something more specific. Getting an accurate diagnosis early is what separates a 4-week recovery from a 6-month one.

This guide covers the most common causes of shoulder pain, how we diagnose and treat them at our Brentwood Bay clinic, and when it's time to stop guessing and get assessed. If you're ready to book now, you can book online here or call 250-223-0200.

Understanding Shoulder Anatomy: Why Diagnosis Matters

The shoulder is made up of three bones — the humerus (upper arm bone), the scapula (shoulder blade), and the clavicle (collarbone) — connected by a network of muscles, tendons, ligaments, and bursae. The glenohumeral joint, where the humerus meets the socket of the scapula, is a ball-and-socket joint with an enormous range of motion. That mobility is a feature, but it also means the joint relies heavily on surrounding soft tissue for stability.

The rotator cuff — a group of four muscles and their tendons — is the primary stabilizer of the shoulder. Above it sits the subacromial space, a narrow corridor through which the rotator cuff tendons and a fluid-filled bursa must pass every time you raise your arm. When any structure in this space becomes inflamed, thickened, or torn, the result is pain — and often, a surprisingly similar set of symptoms regardless of the underlying cause.

This is why shoulder pain is so commonly misdiagnosed. A rotator cuff strain, subacromial bursitis, biceps tendinopathy, and AC joint dysfunction can all produce nearly identical symptoms at first glance. Treatment that works for one often does nothing for the others. A proper clinical examination — including range of motion testing, orthopaedic tests, and muscle strength assessment — is essential to identifying what's actually going on before any treatment begins.

Common Causes of Shoulder Pain

1. Rotator Cuff Strains and Tears

The rotator cuff is the most commonly injured structure in the shoulder. Strains range from minor overuse irritation to partial or full-thickness tears of the tendon tissue itself. The supraspinatus tendon — which runs directly under the acromion — is by far the most frequently affected, accounting for the majority of rotator cuff injuries we see.

Symptoms typically include pain with reaching overhead or across the body, weakness when lifting, and pain that wakes you at night when lying on the affected side. Partial tears often respond very well to conservative care; full-thickness tears may require surgical consultation, which we can help coordinate if needed.

2. Subacromial Bursitis

The subacromial bursa is a small fluid-filled sac that sits between the rotator cuff and the acromion, reducing friction as the tendons glide underneath. When this bursa becomes inflamed — from repetitive overhead activity, poor posture, or direct impact — it swells and takes up space in an already tight corridor.

The result is a painful arc of motion, typically between 60 and 120 degrees of arm elevation. Bursitis is one of the most common causes of shoulder pain in adults over 40, and it often coexists with rotator cuff pathology. Treating only the bursa without addressing underlying movement mechanics rarely produces lasting results.

3. Shoulder Impingement Syndrome

Shoulder impingement occurs when the tendons or bursa in the subacromial space are repeatedly compressed during arm elevation. It's not so much a diagnosis as a mechanical problem — the tendons are getting pinched because there isn't enough space for them to glide freely.

Contributing factors include poor scapular control, forward head posture, muscle imbalances between the chest and upper back, and repetitive overhead work or sport. Hikers carrying heavy packs, cyclists with a forward lean, and desk workers with rounded shoulders are all common presentations in our Brentwood Bay practice. The good news is that impingement responds very well to hands-on treatment and targeted exercise.

4. Frozen Shoulder (Adhesive Capsulitis)

Frozen shoulder is a condition where the capsule surrounding the glenohumeral joint becomes inflamed and progressively thickens, causing a dramatic loss of both active and passive range of motion. It typically develops in three stages — freezing, frozen, and thawing — and can last anywhere from one to three years if left untreated.

It's most common in people between 40 and 60, in women, and in those with diabetes or a history of shoulder immobilization. What makes frozen shoulder particularly frustrating is that it can develop with no obvious injury — patients often notice increasing stiffness after a period of reduced activity or a minor initial irritation. Early treatment significantly shortens the duration and severity.

5. AC Joint Sprain or Dysfunction

The acromioclavicular (AC) joint connects the top of the shoulder blade to the collarbone. It can be sprained by a fall onto an outstretched hand, a direct hit to the shoulder (common in rugby, hockey, or cycling accidents), or through chronic repetitive loading.

AC joint injuries produce pain localized to the top of the shoulder, often with a visible bump in more severe sprains. They're frequently missed in clinical settings because the symptoms can overlap with rotator cuff problems. Specific palpation and orthopaedic testing are required to differentiate the two.

6. Biceps Tendinopathy

The long head of the biceps tendon attaches at the top of the shoulder socket and runs through a groove in the humerus before becoming the biceps muscle. This tendon is frequently irritated in overhead athletes, manual workers, and those with existing rotator cuff pathology — often because the biceps compensates when the rotator cuff isn't doing its job properly.

Symptoms include pain at the front of the shoulder, often reproduced by lifting with the palm up or performing curling movements. Biceps tendinopathy rarely resolves on its own without addressing the underlying mechanics that caused it.

7. Referred Pain from the Cervical Spine or Upper Back

Not all shoulder pain originates in the shoulder itself. The cervical spine refers pain into the shoulder, upper arm, and even down into the hand via the brachial nerve roots. Thoracic spine stiffness and poor upper back mobility can also contribute to altered shoulder mechanics and secondary impingement.

We routinely screen the cervical spine as part of every shoulder assessment. Patients who have had shoulder treatments elsewhere without improvement often respond quickly once the neck component is identified and addressed. This whole-body assessment is central to how we work at Brentwood Chiropractic Group.

8. SLAP Tears and Labral Pathology

The labrum is a ring of fibrocartilage that deepens the shoulder socket and gives the joint additional stability. SLAP (Superior Labrum Anterior to Posterior) tears are common in overhead athletes — swimmers, baseball players, volleyball players — and in anyone who has sustained a significant shoulder trauma.

Symptoms can include a deep aching pain, clicking or catching with movement, and instability with overhead activity. Labral pathology often requires imaging (MRI) to confirm, and while some cases are managed conservatively, others may require surgical evaluation. We'll help you navigate that decision.

How We Treat Shoulder Pain at Brentwood Chiropractic Group

At BCG, we treat shoulder pain using a multi-modal approach — combining hands-on manual therapy, evidence-based exercise rehabilitation, and advanced modalities where indicated. The treatment plan is built around your specific diagnosis, not a generic protocol.

Chiropractic Adjustment and Joint Mobilization

We use targeted manipulation and mobilization of the glenohumeral, AC, and sternoclavicular joints to restore normal joint mechanics and reduce pain. We also address the cervical and thoracic spine, which contribute significantly to shoulder function. Restoring mobility in the neck and upper back often provides immediate relief and makes subsequent shoulder treatment more effective.

Active Release Technique (ART) and Graston

ART is a hands-on soft tissue technique that identifies and treats adhesions and scar tissue within muscles, tendons, and nerves. For the shoulder, it's particularly effective for the rotator cuff muscles, biceps tendon, and the muscles that control scapular movement. Graston instrument-assisted soft tissue mobilization complements ART by breaking down chronic fibrotic tissue that has developed over time.

Shockwave Therapy (ESWT)

Shockwave therapy is one of the most effective evidence-based treatments available for chronic shoulder conditions — including calcific tendinitis, rotator cuff tendinopathy, and persistent bursitis. BCG is one of the few clinics on the Saanich Peninsula offering ESWT. It delivers focused acoustic waves to the affected tissue, stimulating a healing response and reducing chronic pain. Most patients notice significant improvement within 3–5 sessions. See our shockwave therapy for shoulder conditions post for more detail.

Osteopathy

Our osteopaths take a full-body approach to shoulder pain, assessing how posture, rib cage mobility, thoracic spine mechanics, and even the diaphragm may be contributing to restricted shoulder movement. Osteopathic treatment is particularly valuable for frozen shoulder and for patients whose shoulder pain has developed alongside other postural or systemic issues.

Exercise Rehabilitation

Restoring strength and movement control is essential for lasting results. We prescribe a progressive home exercise program targeting rotator cuff strengthening, scapular stabilization, and postural correction — tailored to your specific diagnosis and activity level. Exercises are progressed as you improve, with return-to-sport or return-to-work milestones built in.

Registered Massage Therapy

Registered massage therapy is highly effective for releasing the muscle tension that builds around an injured shoulder — particularly in the upper traps, levator scapulae, pectoralis minor, and the posterior shoulder capsule. Reducing this secondary muscle guarding makes joint and soft tissue treatment more effective and helps patients regain movement faster.

Acupuncture

Acupuncture is a valuable adjunct for shoulder pain, particularly for managing pain and reducing inflammation in the acute phase, or for patients who want to minimize reliance on anti-inflammatory medications. Our licensed acupuncturist works closely with our chiropractors and RMTs to integrate treatment effectively.

Athletic Therapy

For athletes returning to sport after a shoulder injury, our athletic therapist provides sport-specific rehabilitation, movement screening, and return-to-play assessment. Whether you're a swimmer, a paddler, a rower, or a weekend mountain biker, we'll make sure your shoulder is ready for the demands of your activity before you go back to full training.

When Should You See a Chiropractor for Shoulder Pain?

• Pain that has persisted for more than 2–3 weeks without improvement

• Pain that wakes you at night or prevents you from sleeping on the affected side

• Significant weakness when lifting your arm or carrying objects

• A noticeable loss of range of motion — difficulty reaching overhead, behind your back, or across your body

• A painful arc of motion when raising your arm to the side

• Clicking, catching, or grinding in the shoulder joint

• Pain that radiates down the arm or into the hand

• Shoulder pain following a fall, collision, or direct impact

• Stiffness that is progressively worsening over weeks or months

What to Expect at Your First Visit

Your first appointment at Brentwood Chiropractic Group is typically 45–60 minutes. We begin with a thorough history — understanding when the pain started, what aggravates and relieves it, your activity level, and any previous treatments you've tried. We then perform a physical examination including posture analysis, range of motion testing, orthopaedic stress tests, and muscle strength assessment.

Based on the findings, we'll give you a clear diagnosis and a realistic treatment plan — including how many visits we'd expect, what each phase of care will involve, and what to expect in terms of timelines. We don't believe in keeping patients guessing about their recovery. If imaging is warranted, we'll advise you on that as well.

We offer direct billing to most major extended health insurance providers. We also accept ICBC Enhanced Care claims for motor vehicle injuries and WorkSafeBC claims for workplace-related shoulder injuries — with no out-of-pocket cost to you in most cases.
