I have RA, but the tests never showed it. It wasn't until I saw a RA specialist until I got diagnosed.

GO NOW, it gets worse when untreated it really can mess up your joints permanently if you dont get on the right meds.

I can't tell you if you have it however I can tell you what my symptoms where and how I decided to go to the doctor to get a Rheumatologist opinion.  Feet hurt when walking on treadmill, wrists hurt when helping lift father out of wheelchair and bed and then knuckles on right hand began hurting and then the next year the left hand and never seeming to stop.  Then other things became difficult.  Making bed, drying myself off with towels, turning faucet knobs, opening jars. Then one day I saw that my toe on one foot was deformed looking.  I began to wonder what was going on.  However it wasn't until my knuckle on my right hand finally swelled up that I went to the doctor (RA).  She had tests done (RA factor neg) X-rays done and MRI which showed RA cysts in small joints of wrists and some in knuckles.  Started on methotraxate helped some and then it started affecting my liver count and had to add another med Enbrel and all this time pain and swelling was ceasing and I could begin to use my hands wihtout hurting and turning knobs and using my fingers without dropping things.  A big difference. There is no no tell test to determine if you have RA, however if you do and the medication you are put on helps you extremely I would say that it was RA.  And you can really tell the difference when you have to get off it for a couple of weeks then your symptoms all come back.  Best for you to go to a Rheumatologist and check it out.
