RF NEGATIVE/PLAQUENIL HELPING JOINTS

I have been seeing my second rheumatologist, the first was a joke, my tests come out neg for RA. The pain started in my thumbs and wrists, then ankles and big toes, then elbows, shoulders and now knees. all in a 2 1/2 year span. I have minimal swelling but the pain is horrible. My new rheumy put me on plaquenil almost 3 months ago, one a day at first then 2 per day plus ultram and lidocaine patches. He won't diagnose me, I guess he's monitering what the meds do for me and keeps sending me for x-rays and bloodwork. The plaquenil is starting to help, I actually have days when I feel good and can function with minimal pain. I was having alot of difficulty walking and for the past week or so I am walking much better and I can hold things and turn things with little pain. I am very excited to feel better but what does this mean as far as a diagnosis. I am a person who used to live in the gym, work, raised 5 kids, hobbies, just going all the time and then all this joint pain progressing to a point of couch potato and relying on my husband to do trivial things for me cause it hurts too bad to be awake. I am very hopeful that the meds are helping and I will continue to improve and maybe be able to do all the things I used to do, but also scared , my rheumy writes RA on all my ordered tests and mentioned possibly putting me on methotrexate. Does anyone have any idea where this may be going?
