Pain in CIDP

I experienced electric shocks several times a day; feet, hands, abdomen, on the side. I dont take any pain med for this because it only lasts 5-8 seconds at a time and I can tolerate it. But they are pretty annoying. Are these electric shocks a good or bad thing? What does it mean in connection with the nerves? Are the nerves healing or are they still demyelinated? I’ve been getting IVIG for 17 months now. My fingers in right hand are off and on numbish. Does anyone know if these sensory type of symptoms linger on?
