I feel your pain and I'm very sorry to hear about this recent injury. I took suffer from RSD in my BLE and lumbar area. I also have moderate to severe RA to just about every joint in my body. I'm only 40. I had to leave nursing in 2011. The ups and downs of RSD are so very frustrating. Every time we start a new treatment, I have high hopes of relief, that relief never comes. I to so badly want to go back into nursing. But after 3 years of intensive aggressive treatments and the advice of my doctor, I am applying for disability. The application process is a beast itself. I just recently retained an attorney, he feels he can win my case.
I am very sorry you had this set back. Be positive, maybe once this new injury heals, you will be able to take that refresher coarse and get back into nursing.
I have wanted to start a thread pertaining to nurses with RSD, but haven't due to fear of no response. One of these days I will. I just keep going through old threads, hoping to gain some insight.
I wish you the best of luck and a speedy recovery.
