Today is my last IVIG Infusion (hopefully)

I've been doing IVIG treatment for my CIDP, two days, every three weeks, for the past 3 years. Recently it's felt like the IVIG isn't working for me the way it once was. Someone online suggested I talk to my doctor about Vygart hytrulo, a steroid newly approved for CIDP patients. I'm excited to try something new, but of course with that....

I'm worried af.

I'm worried if I have a bad reaction, I'm worried about it hurting and I pass out (apparently it really burns going in), and yes, I'm worried it won't work at all.

I'm also very excited though. What if it does work? What if I have energy again? What if my body does better than it has in years?

Why is it such a thin line between getting your hopes up and having a bleak outlook on life forever? I guess that's just the sick life lol
