I don't know if anyone realizes this or not but Paula has had several fusions in her cervical spine. I was watching a documentary about her life and her doctor was on speaking of it. She even stated or admitted to acting loopy but said she couldn't help it (when American Idol first began). She said she was sitting on her hands to keep from squirming from the pain. Since then I have read that she receives Enbrel injections. Now...how true all of this is...I don't know...I am not her doc and wasn't there. And MAYBE they have told her it is RSD but it could also be Central Pain and on and on it goes. But it DOES appear, at least as of late, that she is NOT acting as loopy or fidegty. So, perhaps the injections are working or whatever it is she is doing. But Vicc is right...she does appear to be moving on and enjoying her life. So, what she is doing or taking seems to be working for her. In my own opinion, I can see a difference for the better...at least so far.
