What could be causing a popping sensation in my neck, involving tendons parallel to my cervical spine, with a history of physical activity and possible previous neck strain?

Popping Sensation in Neck Tendons Parallel to Cervical Spine

Most Likely Diagnosis

This popping sensation involving tendons parallel to your cervical spine is most likely benign tendon or ligament movement over bony prominences, but requires careful evaluation to exclude serious cervical pathology, particularly given your history of physical activity and possible neck strain. 1

Critical Red Flags Requiring Immediate Emergency Evaluation

You need immediate emergency department evaluation if you develop any of the following:

• Severe headache, visual disturbances, or neurological deficits (weakness, numbness, coordination problems) - these suggest vertebral artery dissection, which can occur 12-24 hours after neck hyperextension or rotation and cause stroke 1, 2
• Progressive weakness or bowel/bladder dysfunction - indicates spinal cord compression requiring urgent intervention 3
• Fever with neck pain - raises concern for spinal infection or epidural abscess 4, 3
• Horner syndrome (drooping eyelid, small pupil, decreased sweating on one side of face) - suggests arterial dissection 2

Most Likely Benign Explanations

Cervical Strain with Paraspinal Tendon Movement

The popping sensation you describe most likely represents normal movement of paraspinal tendons or ligaments over cervical vertebrae, particularly if associated with recent physical activity or neck strain. 1

• Cervical strain causes pain, stiffness, and mechanical symptoms from injury to neck structures including paraspinal muscles and tendons 1
• Patients with cervical strain have tenderness along the cervical spine, including paraspinal muscle palpation, and may experience crepitation (popping/cracking sensations) with neck movement 1
• Pain typically worsens with neck extension and rotation 1

Facet Joint Involvement

• Facet joint injury or arthropathy commonly presents with localized, often unilateral pain that may radiate to the trapezius region, with pain worsening during extension and rotation 2
• This can produce clicking or popping sensations as the joint surfaces move 2

When to Seek Prompt Medical Evaluation (Not Emergency)

You should see a physician within 24-48 hours if you have:

• Persistent neck pain lasting more than 1-2 weeks despite conservative management 1
• Pain radiating down your arm with numbness or tingling - suggests cervical radiculopathy 5
• Occipital or suboccipital headaches that worsen with neck movement 1
• Significant limitation of cervical motion or severe pain with movement 1
• History of recent neck manipulation or self-manipulation - increases risk of arterial dissection 2, 6

Conservative Management Approach

If you have no red flags, initial conservative management is appropriate:

• NSAIDs (ibuprofen or naproxen) for pain and inflammation 4, 5
• Gentle range-of-motion exercises and stretching, avoiding forceful neck manipulation 5, 6
• Physical therapy involving strengthening and stretching exercises 5
• Avoid repetitive neck cracking or self-manipulation, as this increases risk of arterial injury 2, 6

Imaging Recommendations

Imaging is NOT initially required if you have no red flags and symptoms are improving with conservative management. 1

However, MRI cervical spine without contrast is indicated if:

• Symptoms persist beyond 4-6 weeks despite conservative treatment 1, 5
• Any red flag symptoms develop 1, 3
• Clinical suspicion for ligamentous injury or instability remains high 1

CT has limited utility for soft tissue evaluation and should not be first-line imaging for non-traumatic neck symptoms. 1

Critical Pitfalls to Avoid

• Do not assume all popping sensations are benign - vertebral artery dissection can present with isolated neck pain initially, before neurological symptoms develop 1, 2
• Do not perform or allow aggressive neck manipulation, as physical therapists and chiropractors have caused arterial dissections, though rarely 6
• Do not ignore persistent symptoms beyond 4-6 weeks - this warrants imaging to exclude underlying pathology 1, 5
• Do not rely on plain radiographs alone if serious pathology is suspected - they miss most soft tissue injuries and have only 36% sensitivity for cervical injuries 1

Specific Considerations for Your History

Given your history of physical activity and possible previous neck strain:

• Capsular ligament laxity from prior injury can cause chronic instability and mechanical symptoms including popping sensations 7
• Whiplash-associated disorders can cause persistent symptoms even when imaging appears normal 1, 7
• These conditions typically improve with physical therapy focused on strengthening and stabilization 7, 5
