@johnbishop I am not @howshu, but I have had shocks throughout my body occasionally for 81 years. They seem to hit from my left big toe and go to the top of my head. They hit a few times per year. My major diagnoses that would seem to count here include Gelsolin, LGMD2m with Walker-Warburg, Epilepsy, RYR1, RYR2, leukemia, disappearing cerebellum white matter, rheumatoid arthritis, Clarkson's Disease.
