Hi. With disability I think some depends on luck and less of issues. I know some people I was inpatient with for eating disorder had been on it for a long time and others who were more extreme couldn't get it. I had thought of trying when I had that issue and have the paper work I had to fill out. I would try to talk to your principle so if things don't work out you can have your docs start the paper work. I'm sure it can take a while like all things I would think especiallly since you have been having the ivig you may have a lot of luck with coverage. I do think your health is number 1 and rushing to work and getting overwhelmed physically and mentally may make things worse in the long run. Not with this issue but in my past I have rushed recovery to end up backsliding. Your health is number 1 and state your needs. Take care
