Intermittent & Progressive?

I get confused by the intermittent and progressive part of CIDP. First, I tend to be very literal about things, so I may just be missing the point. 😀
As I read the stories it seems like some people progress very slowly and others progress quickly.

My symptoms have never gone completely away. I have days where I am getting around better and then days where it is worse. It doesn’t seem to change daily, but I have a few good days, and a longer period of bad.

Can the IV steroids make it so a person feels better for awhile?

I don’t know that I understand how CIDP progresses yet.

Just looking for more insight.

Thanks!
