keep in mind that none of the people who answer questions here are doctors and that means that we are not experts in blood pathology, either. We have an excellent post about blood tests that can give you more information.
That said, rheumatoid arthritis is notorious for being hard to pin down in blood tests, especially the beginning. Most good rheumatologists will diagnose RA by medical history and physical exam and pay very little attention to the blood tests. I would recommend you ask for a second opinion and if you believe you have a type of inflammatory arthritis, keep pushing. Your other symptoms including the sore throat, nasal discharge and hair loss on knots typically symptoms of RA, but it is clear that something is going on. I would recommend you ask your doctor for more tests to investigate the other symptoms.
