I ran into the same roadblocks...we are poor risks and facilities don't wish to hire us after on the job (or other) injuries. Makes us feel like packmules or something doesn't it.
My suggestion: If you are still physically capable of doing the work, try agencies...I'm finally back to work, making my own schedule, making more $$ and calling my own shots. You can even buy your own health insurance now...we don't NEED facilities to employ us...we can do our own thing and go self employed too if we don't want to work agency.
Also check out alternative nursing careers...things you may not have considered. Start with your strengths...look at compatible nursing jobs. It is important for you to heal emotionally so you can promote/present yourself in a positive light...so take care of yourself and 'get well' in all aspects!
Best wishes and don't give in! (The facilities want us to slink off...if you can fight them, do it) But...do what is best for YOU.
