I have thought of this issue as well. I think for a potential employer I would not say anything until I had to. For ex at the time if I could not do something because of my condition. I feel with an employer if you stated health problems especially since many are unfamiliar with rsd it will impact getting hired. Especially in this day when so many people are looking for jobs.
Now people in my life if a friend or family I tell them what I face and try to be open and honest.
What type of job will you look for? Maybe still with animals but in a different line of work?
