I have a couple questions to add: have you had your ANA, sed rate, and CRP checked? These can be up in a lot of autoimmune diseases. It's not unusual for autoimmune diseases to get set off by viruses. Have you had x-rays of your knees recently? Some people have degeneration at the joint without positive bloodwork for RA. Also, many nurses and doctors forget this, but an oral temp of 99.4 actually is a fever. Fever is defined as a core body temp of 100.4 or more. If your temp is taken orally, it is 1 degree lower than your core temp, which in your case means 99.4 + 1= 100.4. Keep looking for a cause! I'm so sorry your life has fallen apart like this.
Hi and welcome to MedHelp Autoimmune Forum.
There are what they call lupus look alikes. They are lymes, bartonella, rocky mountain fever, chronic fatigue, fibromyalgia, and MS. It doesn't sound like MS. But I would suggest that you be tested for the others.
How many times did they test for lupus? Just know that the RF (RA) could be neg for quite some time and still have RA. I have a friend who had quite a struggle getting a dx of RA. But her joints would swell horribly, just not while she was in the dr. office.
I would like to ask a few questions. Do you have:
facial rash,
mouth sores,
protein in urine,
diarrhea,
heart burn,
muscle weakness,
bone pain,
does being in the sun cause your joint pain to become worse?
Have they tested your vit D level?
