GBS or MS?
I have a theory you might want to consider. For people who once had GBS & then their nerves remyelinated, those nerves are never quite as strong as their original nerves were at birth. So any trauma to the body, such as childbirth, can temporarily weaken those nerves. Having a baby or a young child is exhausting, & might trigger a “flare-up” of some of the GBS residuals. It could be possible that you just need more rest? I know, easier said than done. I am just suggesting the possibility that there is no new illness, just residuals acting up from when you had GBS before.
BTW where is Underwood? I live in Minnesota as well, up north on the Iron Range in Virgina. Welcome to our forum…
