Persistent pain after trigeminal nerve injury is not simply the result of damaged tissue. It reflects complex changes throughout the nervous system, including altered nerve signaling, reduced inhibitory control, peripheral and central sensitization, and long-term neuroplasticity.
These mechanisms help explain why neuropathic pain may continue long after tissues have healed and why conventional painkillers are often ineffective. Understanding the biology of chronic pain is an important step toward finding appropriate treatment and reducing self-blame.
