I have joint pain, anemia, swollen lymph node, and fever. Is rheumatoid arthritis the cause?

Hi doctor,

I am a 22-year-old female. My height is 5 feet 3 inches and my weight is 97 lbs. I started experiencing pain in my joints an year ago. The pain continued and increased in intensity. Before eight months I was told that my blood was a bit low. I fractured my arm very easily seven months ago. After that the pain was a bit better since I was taking Dipirona. For my blood I was given Iron tablets, Folic acid, Vitamin C, and Multivitamins. Four months back I was hospitalized for fever, joint pain, and anemia. I was diagnosed with anemia due to deficiency of iron. The joint pain continued and was later diagnosed with rheumatoid arthritis. My rheumatoid arthritis factor, erythrocyte sedimentation rate were high. I have swollen and inflamed joints and still had anemia. I was given therapy of ozone gas for 20 days and took Prednisone for roughly three months. Now I am told that I do not have arthritis and I am confused. My symptoms now include slight muscle or joint pain, anemia, swollen lymph nodes, low grade fever only for a few days not more than three, fatigue, and sore throat at night. I have a raised spot that appears and disappears on my chest (not sure if this is important) Leukogram reading was 5.1*10⁹, lymphocytes- 0.32, platelets- 0.67, eosinophil- 0.3*10⁹, MCV- 79.3 ,MCHC- 29.7, globulin- 5.3 g/dL, LDH- 649.7 hematocrit from 0.28 to 0.33. I hope I was clear with my query.
