September marks Pain Awareness Month, a time to challenge the common assumption that pain always signifies physical injury. For millions suffering from chronic pain, the source may lie not in tissue damage but in the nervous system itself. Dr. Eric Anderson, neurologist and Chief Medical Officer of Lin Health, a virtual care company based in Denver, emphasizes that persistent pain can become a disease of its own, driven by a hypersensitive alarm system in the brain.
“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, where the nervous system amplifies pain signals, playing a major role in conditions like fibromyalgia, chronic migraine, sciatica, and irritable bowel syndrome.
Dr. Anderson likens the process to a fire alarm that has become overly sensitive. “That high-pitched shriek is definitely real, but it may be going off when there isn't actually a fire,” he explains. The good news, he adds, is that evidence-based approaches can retrain the brain to reduce this overreaction. “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 is central to Lin Health’s model, which offers a medication-free virtual program combining behavioral therapy, one-on-one coaching, and structured daily modules delivered through an interactive app. The program aims to address the nervous system processes that contribute to persistent pain, offering a new avenue for patients who have not found relief through traditional treatments.
For Pain Awareness Month, Dr. Anderson hopes to raise awareness that understanding central sensitization can be 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,” he says. This shift in perspective could lead to more targeted and successful interventions, moving beyond symptom management toward measurable recovery.
Lin Health, founded in 2021, partners with leading health systems such as Mayo Clinic and WellSpan Health to deliver this multidisciplinary care. The platform integrates physician evaluation, structured behavioral pain recovery, personalized coaching, and continuous patient engagement, following clinical guidelines that are often difficult to implement in traditional settings due to access limitations and fragmented care pathways. By bridging this gap, Lin Health aims to make this highly effective intervention scalable, affordable, and broadly covered by insurance.
As the medical community recognizes the role of central sensitization in chronic pain, treatments like those offered by Lin Health represent a promising evolution. By focusing on the brain’s role in pain perception, patients may find new hope in managing conditions that have long been misunderstood.
