i am officially ideopathic although i know it has a toxic cause due to exposure to numerous toxic substances(not medicines) nine years ago. By the time i realized what i had was PN it was really too late to test for those substances.

Tulips i have sensory motor PN also and i also get fasciculation in my leg muscles often. I also get muscle jerks in my arms and legs. The strength in my legs and arms has not diminshed that much. I also get severe cramps if i dont keep up with taking magnesium or drinking enough water. My toes will also cramp if i contract them. My feet are pretty much dead numb now with numbness going above my knees. At the same time though when i stand or walk it feels like i am walking on broken bones.
