My sister is 33 years old. For the last few years, she has been experiencing joint pain and weight loss. We did a blood test and RA factor is negative. Please suggest what we can do for this?

Even with negative RA factor, autoimmune arthritis is possible. Consider ANA and anti CCP testing. Weight loss should also be evaluated with basic blood work and possibly imaging.

Dr. Kamran Suggests...

Take a ANTI NUCLEAR ANTIBODY (ANA) Test or Take a Anti CCP Test (Cyclic Citrullinated Peptide) Test

I have pain in my body from neck to hip joints and shoulders after sitting a few minutes, and sometimes I also get headaches. I underwent treatment and my blood report shows abnormal results: total WBC count is 12,700 cells per cumm, ESR is 52 mm per h, and RA factor is 4.8 IU per ml. My doctor prescribed medicine without explaining the report. Can anyone please explain my report? Is there anything serious in my blood report? Are these symptoms of cancer? Please answer and suggest what is better for me.

I suffered from viral fever one month ago. After 2 to 3 days I got red rashes all over my body. Dengue and Chikungunya tests were negative. Now, since one month I am suffering from acute joint pain. My blood report for ANA is strongly positive. Please suggest?
