Rethinking Pain: When the Alarm System Itself Becomes the Problem

September is Pain Awareness Month, a time to challenge a fundamental assumption about pain: that it always signals tissue damage. For millions of people, pain persists long after an injury has healed, or even without any identifiable injury. According to Dr. Eric Anderson, a neurologist and Chief Medical Officer of Lin Health, a virtual healthcare company based in Denver, sometimes the pain itself is the disease.

"Pain is always real, but it doesn't always mean there is ongoing damage in the body," says Dr. Anderson. "Sometimes, the brain and nervous system can become stuck in a persistent pain-alarm loop, continuing to send danger signals long after an injury has healed, or when there is no injury at all."

This phenomenon is known as central sensitization, a condition where the nervous system becomes hyper-reactive and amplifies pain signals. It plays a significant role in chronic conditions such as fibromyalgia, chronic migraine, sciatica, and irritable bowel syndrome (IBS). Dr. Anderson uses an analogy: "Think of it like a fire alarm that has become too sensitive. That high-pitched shriek is definitely real, but it may be going off when there isn't actually a fire."

The good news, he says, is that evidence-based approaches can help recalibrate the nervous system. "The pain is very real, and the goal is to help the nervous system become less reactive to signals that it has learned to interpret as dangerous." This brain-first approach, which Lin Health offers, focuses on retraining the brain and nervous system to reduce pain perception. The program is medication-free, delivered virtually through an interactive app, and combines behavioral therapy, one-on-one coaching, and structured daily modules.

For Pain Awareness Month, Dr. Anderson emphasizes that understanding central sensitization is a crucial first step for those living with persistent pain. "The pain is always real, but understanding why it persists may open the door to more effective approaches to treatment."

Lin Health, founded in 2021, is a physician-led virtual care platform that partners with health systems like Mayo Clinic and WellSpan Health. Its model integrates physician evaluation, behavioral pain recovery, personalized coaching, and continuous engagement, aiming to address the biological, behavioral, and social drivers of chronic pain. "This approach aligns with clinical guidelines but is rarely implemented effectively in traditional systems due to access limitations, clinician shortages, and fragmented care pathways," says Dr. Anderson. By delivering scalable and affordable care, Lin Health aims to make this intervention accessible to more patients.

As pain awareness grows, the message is clear: understanding the brain's role in chronic pain could transform treatment approaches and offer hope to those who have suffered in silence.
