A fellow Aussie
I grew up in Melbourne, have been in queensland for nearly 10 years. I got GBS in July. Unlike you, mine was a severe case requiring ventilation. I was in ICU for 4 weeks and spent 7 weeks in hospital altogether, although I have been lucky and had a pretty quick recovery and require no ongoing physio. I was paralysed on both sides however my right definitely recovered quicker (i am also right handed) I had Miller Fisher variant which affected my facial nerves and funnily enough the left side of my face recovered a lot quicker. So i would say that recovery does vary on different sides of the body. I think why they say it is symmetrical is generally both sides of the body are affected unlike a stoke where only one side is normally affected.
When i was being discharged from hospital the OT did a test of fine motor skills. I had to put pegs in a puzzle and actually scored in the 95th pertcentile so I would say there is a good chance of complete recovery, it is just a matter of time.
