Daughter was diagnosed with RA in Dec age 24. She has had three cortisone steroid injection. On methotrexate and hydrocloquine. In 8 weeks we will know if mtx is working as it is the steroids that are doing the job just now. She has been suffering from hot and cold sweats. Is this a sign of ra or the Meds. How long will she take mtx as I heard as it is a chemo drug she will have to change at some point ?
