I starting seeing a rheumatologist over a year ago. I had one test that came back negative for RA. I have researched and more testing is usually involved in regard to testing for RA. I have all of the signs and symtoms, and the disease has progressed 180% in less than one year. Not all people with rherumatioid arthritis test positive for the rheumatoid factor, especially early in the disease. My mother has Ra and I believe that I do as well but the rheumatologist disputes this and does not seem to take me or my questions about the pain, swelling,etc. as important. What would be the best way to get an accurate diagnosis? I have been receiving cortisone injections in my shoulders for about nine months but at best the relief only lasts about one month. I do not know where to get the best information.
