All of these symptoms sound horrible!! I feel that I have no right complaining about mine. I too work in a hospital and my first thought was adrenal issues...but you said that was ruled out. My only other thought is advanced lymes. Have you been tested for that? Did you have a spinal? I'm sure you don't want everyone at work knowing what is going on, but you have some excellent resources where you are. It is frustrating. Good luck to you.
