Numbness in the Face and Hand – Neurological Insights into Integrated Upper Cervical and TMJ Treatment

by Son PMR(Physical medicine & Rehabilitation ) & Chiropractic Clinic in Seoul

A patient recently visited Son Cheolho Rehabilitation Medicine Clinic with complaints of persistent numbness in the right side of the face and right hand lasting over a year.
Despite having undergone a brain MRI at a university hospital, no significant abnormalities were found. The patient also tried acupuncture therapy, but there was no noticeable improvement.

In such cases, it is essential to look beyond structural abnormalities in the brain and consider the overall functional balance of the nervous system.

Treatment Approach: Integrated Care for the Upper Cervical Spine and TMJ

Upon functional assessment, we observed misalignment of the upper cervical spine (C1–C2) as well as muscle tension and asymmetry around the temporomandibular joint (TMJ).
We implemented a combined approach, including:

  • Upper cervical chiropractic adjustments

  • Soft tissue stabilization around the jaw and upper neck

  • Targeted injection therapy to support tissue recovery and improve function

Neurological Mechanisms Involved

The upper cervical spine and TMJ are not just structural elements—they play key roles in neurological regulation. Here are several pathways through which these regions may affect facial and hand sensation:

  • Upper Cervical Spine and Brainstem Relationship
    The C1–C2 area lies near vital structures like the medulla oblongata and spinal trigeminal nucleus, both of which are involved in processing facial sensation.

  • Trigeminal and Cervical Nerve Overlap
    The trigeminal nerve, responsible for facial sensation, extends downward to the C2–C4 spinal levels, meaning dysfunction in the upper cervical region can influence trigeminal nerve activity.

  • TMJ Imbalance and Trigeminal Sensitization
    Imbalance or tightness in the masseter and temporalis muscles surrounding the TMJ may lead to trigeminal nerve sensitization, contributing to facial numbness and autonomic imbalance.

  • Cervical Spine Tension and Brachial Plexus Irritation
    Misalignment of the upper cervical spine may affect dural tension and influence the brachial plexus, potentially causing altered sensation in the hand or arm.

Patient Outcome

Through integrated care focused on upper cervical correction and TMJ-related soft tissue stabilization,
the patient began to experience gradual relief of numbness and improved comfort in daily life.

 What is Central Sensitization? by Son PMR(Physical medicine & Rehabilitation ) & Chiropractic Clinic in Seoul Central sensitization refers to a condition where the brain and spinal cord become abnormally sensitive to pain signals following an injury or inflammation. In simpler terms, the pathways that perceive pain become overly reactive, causing individuals to experience excessive pain from minor stimuli or persistent pain even after healing . Key Features of Central Sensitization Amplified pain responses (Allodynia) Pain is felt even with non-painful stimuli, such as light touch or gentle movement. Increased pain sensitivity (Hyperalgesia) Painful stimuli feel much more intense than usual. Persistent pain Pain can continue even after the original injury or inflammation has resolved. How Central Sensitization Develops Peripheral nerve injury or inflammation → Continuous transmission of pain signals to the spinal cord and brain → Hyperexcitab...

A Case of Hand Numbness Improved through Upper Cervical and Integrative Treatment by Son PMR(Physical medicine & Rehabilitation ) & Chiropractic Clinic in Seoul  A patient recently visited our clinic complaining of persistent numbness in both hands. This individual had worked in a physically demanding job for many years, frequently using their hands and arms in repetitive tasks. Despite receiving various treatments at multiple clinics, the symptoms either temporarily improved or continued to recur. Referred by an acquaintance, the patient underwent a comprehensive evaluation at our clinic, including a detailed consultation, postural assessment, and upper cervical spine (C1 and C2) functional testing. It was found that subtle misalignments in the upper cervical spine were likely contributing to ongoing nerve irritation, muscular tension, and postural imbalance — all of which could aggravate hand numbness. Our treatment approach combined gentle upper cervical chiropractic ...
