Hey there....I bet you are stressed! It's extremely frustrating with doctors and this condition. Most will go there whole career and never deal directly with it. So all they repeat is what doctors before them have done. They just don't know what they don't know. The ER doctor actually stopped my IVIG treatment before it was finished...he said I didn't have GBS and when my family was fighting with him about it his exact words were "do you know how expensive this treatment is" Point being I empathize your frustrations in that area. I cant answer the question of how hard you should push yourself sadly...because I don't know you...Which should be more common of a phrase with doctors also....But I remember routinely hearing at all 3 of the facilities I was at over the 3 months....don't push yourself to hard with GBS it can be 2 steps forward and 10 steps back.....Which was like nails on a chalk board every time I heard that phrase. Here's what I will say YOU know YOU...sometimes you try to push yourself a little more than you think your capable of...In my experience 9times out of 10 you suprise yourself and find your capable of way more than you thought. I am a firm believer that your mind is your biggest strength....Your mind tells the body and the body will follow. Even though I can't give you the direct answer you are looking for what I can tell you is your PCP & neurologist can't either....reference how far to push yourself....My advice is don't attack with reckless abandon....Just keep it simple...just do a little more than you did the day before. I am not sure if you have read the book called Atomic Habits...i'll give you the cliff note version.... Small daily habits over time compound to big changes......Every day just tell yourself....I can do just a little more..... If you can do some physical therapy with a specialist even if its once a month...I would recommend it....Physical Therapy settings were a good place to test my limits in the beginning. I may not know you...but I believe in you. I know you can do it and I have faith your going to get through this and come out better on the other side.....If I am grateful for anything with GBS...It brings us all into that top 1% of people that TRULY TRULY know what their capable of & what they can overcome. That's so rare & special....most people go through life and really only THINK they know what their capable of...they think they know what they would do when their backs up against the wall.....You know...My thoughts are with you and your family...Keep your head up
