Do you think working with a knee walker would be possible?

Well, you all have given me some good ideas. I need to talk to HR and NM to see if they are willing to work with me for all of this. I am in a pickle, cause it hurts tremendously to be on them 12 hours now, but I can't afford the time off, so I struggle through it. NM already knows that I am in pain and have been to MD about this and will need surgery, so now I have put this off as long as possible and I need to sit down and talk about the details of work for me post-op.
I don't have disability insurance. I looked into it, but it seems that it would not kick in for me until another 12 months pass because it is pre-existing. Ugh. I don't think I can wait another year.
Oldnurse, I am sorry you are in the same predicament. Keeping my fingers crossed that we will find solutions to our work/surgery issues.
