Shoulder Pain and Upper Back Tightness After a Car Accident
Provo, Utah — Cervical Radiculopathy vs. Shoulder Injury. Fellowship Differential Diagnosis.
Shoulder pain after a car accident requires careful differentiation: is the shoulder itself injured, or is the pain coming from a cervical nerve root? The treatment is completely different. This distinction is frequently missed.
Cervical vs. Shoulder Origin — Why It Matters
The C5 and C6 nerve roots of the cervical spine refer pain into the shoulder, upper arm, and lateral forearm. A cervical disc herniation or facet injury at these levels — common in car accidents — can produce shoulder pain, weakness, and limited arm mobility that is clinically indistinguishable from a rotator cuff tear if the cervical spine is not evaluated.
Many patients after a car accident are sent for shoulder MRI or orthopedic evaluation when the true source is a cervical nerve root compression. If the cervical spine is not evaluated and treated, the shoulder symptoms will not resolve regardless of what is done to the shoulder.
Seatbelt and Airbag Injuries
The seatbelt loads the shoulder and chest in a collision, and the airbag creates a rapid extension force on the arm and shoulder. True shoulder joint injuries — acromioclavicular separation, labral tears, rotator cuff damage — can occur from these mechanisms. Our evaluation distinguishes cervical referral from true glenohumeral pathology so the correct structure is treated from the start.
Symptoms and Signs
Cervical Origin Signs
- Shoulder pain with neck movements
- Radiating into arm or fingers
- Numbness pattern in arm
- Associated neck stiffness
Shoulder Joint Signs
- Pain with arm elevation
- Weakness in overhead movements
- Pain at the AC joint
- Night pain (rotator cuff)
Upper Back Pattern
- Trapezius muscle spasm
- Pain between shoulder blades
- Tightness with arm movement
- Scapular pain or winging
Fellowship-Level Trauma Evaluation
Our doctors hold a Fellowship in Spinal Biomechanics and Trauma (FSBT) — one of the highest post-doctoral credentials available in chiropractic, including advanced training in trauma evaluation, MRI interpretation, and motion X-ray analysis. We have been serving Utah County since 1999 and work directly with personal injury attorneys, local MRI facilities, and spine specialists.
If you were in a car accident, your injury documentation begins on day one. The longer you wait, the harder it is to establish a clear relationship between the collision and your injuries. We can evaluate you, document the clinical findings thoroughly, and coordinate with your attorney and insurance carrier.

Why Shoulder Pain After a Crash Requires Careful Diagnosis
Shoulder pain following a motor vehicle collision has multiple possible sources — the cervical nerve roots, the shoulder joint itself, or both simultaneously. Research confirms that misidentifying the primary driver leads to failed treatment.
Wainner & Gill — Cervical Radiculopathy Diagnosis
A clinical prediction rule for cervical radiculopathy identified four key examination findings — including Spurling’s test, distraction relief, and cervical rotation limitation — that when combined have high specificity for C5-C6 nerve root compression producing referred shoulder and arm symptoms.
Abbed & Coumans — Cervical Radiculopathy Patterns
The C5 and C6 nerve roots — the most commonly compressed in cervical disc herniation — produce pain and weakness patterns that exactly mimic rotator cuff pathology, subacromial impingement, and acromioclavicular joint injury, making accurate diagnosis essential before any shoulder treatment is initiated.
Carette & Fehlings — Treatment of Cervical Radiculopathy
A review in the New England Journal of Medicine confirmed that the majority of cervical radiculopathy cases resolve with conservative care — specifically spinal manipulation and targeted mobilization — without requiring surgical intervention, even when initial symptoms are severe.
