Arthra

I went to the General doctor because a further business i had and i also told him about the pain on my hands I’ve felt. I did an X-ray and he said didn’t show anything, but my blood test (which was for checking my joints) was positive. Then he referred me to a rheumatoid doctor (or something like that). he didn’t know what could be once the x ray was ok. So, it’s not tendonitis, right? could it be arthiritis or carpal tunnel?
I don’t have insurance and the appointment with the other doctor will be just in 3 months, which I know it’s too far and it can leave with a recurring problem.
What could I do to avoid getting worse? I am a house cleaner and i know it’s because of this. But i can’t leave my job. which kind of those “wrist gloves” i could use? i was by one the compress the wrist, but i just read it shouldn’t be tight if it’s carpal syndrome.
is here an anti inflammatory over the counter i could use? i used bengay and in the beginning worked out, but now, it makes the pain even worse.
Thanks for the initially answer, but i don’t want to take pain killers, i want to fix it, or at least get rid of the inflammation.
the x ray was of the wrist and fingers
