Idiopathic Axonal Sensorimotor PN (though on any given day I feel I’ve left out a word in that description) . It has been confirmed by EMG. Though it came on suddenly (good health to weakness & wheelchair bound in 10 days), it was accompanied with a kidney/UTI infection but they said Guillain Barre was negative. They say it’s “possible” I could have some variant of it, but basically everything they knew how to test came up negative - hence Idiopathic. Good luck with your IVIG if you choose that option, and I hope you’re proactive with managing your symptoms. PT got me out of my wheelchair after 6 months and I’ve maintained for over 6 years and am so grateful for that!
