I am by no means an expert on Lupus, But I did want to give you some information that I have learned over the last few years. I, like you, am a nurse and when all this started I knew very little about Lupus. When I was diagnosed the first time (long story) my wonderful doctor (Internist) told me that I would probably know way more about Lupus than he ever would because I had personal stakes in it and that was ok. Well back to the subject at hand. Just about everything I have ever read about Lupus says that there is NOT one definitve test to say for sure that it is absolutely Lupus. The American College of Rheumatology has criteria that aid in the diagnosos and if you look at some of Saysusie's posts(the moderator) she is very good about explaining this among other things related to Lupus. Now the symptoms you described sound very suspicious of Lupus and if I were you I would insist that your GP refer to a Rheumatologist. They specialize in this and are your best bet for help with finding out what is wrong. Just to warn you also that Lupus has a nick-name "the Great Imitator" because many of its symptoms are similar to other diseases so it can be extremely hard to diagnose. It may take a while to get answers. So don't give up. You know your body better than anyone else and you need to be your own advocate and insist that they find out what is wrong. Well I hope this helps. Good Luck and keep us posted.
