Among the more curious sensations linked with multiple sclerosis, Lhermitte’s Sign MS is often described as an “electric shock” that shoots down the spine when you bend your neck forward. It can travel into the arms, legs, or fingers — sudden, sharp, and gone in a blink, yet strangely memorable.
Lhermitte’s Sign MS occurs when inflammation or demyelination affects the cervical spinal cord. As nerve pathways lose their protective coating, electrical signals misfire, producing that jolt-like feeling. It’s harmless in itself but can be unsettling, especially the first time it happens.
There’s no single treatment for Lhermitte’s Sign MS, but cooling, posture awareness, and gentle physiotherapy can reduce its frequency. For more persistent episodes, neurologists may prescribe medication to calm over-active nerve signals.
Think of it less as a threat and more as feedback — the nervous system’s way of reminding you it’s under strain. Understanding the cause can turn that spark from a shock into information, helping you adapt and stay in control.
