Guillain-Barré syndrome is a rare autoimmune syndrome in which the immune system attacks one’s nerves.

Rosenbaum himself uploaded a series of videos to his Instagram Story as he reflected on the shocking revelation.

“Things you do every day, like picking up this phone, or buttoning buttons, tying shoelaces, putting on deodorant, just can’t do it,” he continued. “Picking up my kids, can’t do it. Wiping your a--, maybe TMI, but might have Ashley assist on the next one. Can’t really believe it.”

“Next steps are figure out if I have plateaued — which I think I have — on my symptoms and definitely stay another night in the hospital,” Rosenbaum said in a medical update. “[I] know there’s a lot of physical therapy.”

Hours later, Rosenbaum went on to note that he finished his second round of treatment and said he felt “pretty much the same as I have all day.”

“Hopefully I am on the road to recovery… I’m fortunate enough where we caught it early enough to start a treatment early enough where we can now start recovery, but I will know tomorrow once I speak to the doctor,” he said.
