Does anyone experience this? I'm not talking about Lhermitte's sign (which I also get) as it's much more widespread and not triggered by neck movement. It's usually worse when my MS is generally worse and my fatigue levels are high. Sitting still it calms down a bit, but when I get up to do something like put laundry away, get dressed or make a cuppa the electrical/numb waves start in my chest mostly and radiate across my body, up to my face and down my limbs, particularly my left side. The sensation also comes with a feeling of weakness and loss of balance. I usually can't push past it as it just pushes back harder.
