I Have Been Running A Fever Every Day For Over

I have been running a fever every day for over a year. it is usually around 100 degrees sometimes a little higher. I went to a dr. and she ran a lot of blood tests. she said my ANA came back positive and speckled and that she would call me in a few days to set up an apt with a rheumatologist. The only symptom other than the fever is I am always tired... ALWAYS. But she never called and I just kind of let it go. Is this something I should be worried about and what exactly does a positive and speckled ANA mean?
