I got my test results back. Negative on ANA, and negative on RF, but a very high CRP. 

My primary care doctor said that regardless of the ANA and RF results, he wants me to see the Rheumatologist. Partially because the CRP is alarmingly high, and partially becuase based on the symptoms he is still very concerned about an autoimmune disorder. He also pointed out that not all lupus and rheumatoid arthritis patients will have a positive result. (I googled it, and 5% of lupus patients have a negative ANA result, and about 38% of Rheumatoid Arthritis patients have a negative RF. So... way more likely with Rheumatoid Arthritis).
