Backsliding…

If you have too much trouble with backsliding, then you could possibly have CIDP, the chronic form of GBS. But you are still so early in your GBS, many don’t even peak with getting worse until after 4 weeks. I would look at recovery in terms of months, not days or weeks. At least your upper body is doing well strengthwise. You just need to be patient, believe me I know how hard that can be.
