Need some info on Rheumetoid Arthritis

My name is Tiffany and I am 28 yrs old. I recently went to the doctor for severe knee pain. I have been having stiffness and joint pain for a couple years but all other appts to the doctor turned nothing up. So they ran tons of bloodowrk and xrays, which almost everything came back good. However I had a bloodtest called ANA come back positive, they are thinking Lupus or RA....but my test for RA came back negative. So my question is....could it still be RA?? HAs anyone ever had the doctor's test come back negative but when they went to the Rheumetologist it was proven to be RA??

I am sorry you are in pain but glad you found us.  Yes, it is possible to test negative for the RA antibodies and still have RA.  It is also possible to have a false positive test result.  Additional tests may be needed, exams, x-rays, MRIs and a bone and joint scan to determine what is going on.  At the top of this forum is a message on preparing for a rheumy visit.  Since it sounds like you have not yet been to one, I urge you to read it so you can get the most from your appt.  Please keep us posted on how you are doing, other symptoms you have (even if they do not seem related) and what you find out.  We are here to help in any way we can.
