I have pain and swelling in my right wrist. Is it due to rheumatoid arthritis?

Hi doctor,

I am a 27-year-old female, and I was diagnosed with RA late last year. It has been persistent in my wrists this year. I was told to take Zycel 200 mg, but I feel something else could be wrong, as the pain and swelling are only in the wrists, more in the right hand. In my country, we do not have doctors to help. I read about carpal tunnel syndrome, and I need your help with it. I had sudden joint pain two years back, and it lasted for four months negative for RA and the pain suddenly stopped. And last year, I had sudden migratory joint pain with stiffness and swelling. I tested negative for RF then, and recently my RF factor was positive, so they put me on Zycel. From the beginning of this year, the pain has been persistent on my right wrist only with swelling and stiffness, which affects the fingers too. And on a few occasions, it attacks the left wrist or leg joints only.
