Seronegative and unsure about medication

Hello! I am new to this site, so my question my have been answered before and I apologize if this is the case. I was diagnosed a couple of years ago with RA based on a bad wrist. My wrist had been hurting really bad and my doctor noticed I'd lost range of motion in it, so he sent me to a rheumatologist. After a thorough exam and blood work, she diagnosed me with RA. My issue is that I basically have 2 sore wrists (the other started hurting 6 months or so ago) and that's about it. All of my bloodwork is well within normal ranges, showing no inflammation whatsoever. When I read about RA, I just can't relate to the symptoms other than my wrist pain. I get out of bed easily in the morning and I'm at the gym within 40 minutes. I have no problems with fatigue unless I haven't slept well. I am on Plaquenil but my doctor thinks I need to add methotrexate because she thinks that my disease is moderate. I have been fighting her on taking anything else because of the possible side effects. I have read so many stories where doctors won't give medication because they aren't convinced that the person has RA, but I'm in the opposite camp. She wants me to take drugs that I don't want to take, because all things considered, I feel pretty good. Is there anyone out there who has had the same experience? Thanks for letting me vent!
