31 going on 90

I went to the doctor back in May because my wrist kept hurting and three of my fingers kept going numb and they told me I had carpal tunnel and gave me a brace to wear and told me to take b12.... well, I wore the brace awhile but it made it hurt worse so I stopped using it. Occasionally my wrist will hurt but nothing too major...

Well, the past couple weeks my hands, both of them, have been giving me hell.. In the mornings when i first wake up they are so stiff i can barely use them... like they feel puffy or something... like my fingers are too fat to make a fist if that makes sense..

at work the past month I've been painting pretty much everyday, and by about 4 everyday my hands hurt so bad I can barely stand it... and they claw up on me... like they'll keep the shape of how I was holding the roller or brush I was using and stay that way til I relax for a few enough to straighten them back out again.

I realize popping my knuckles is doing damage and I've been doing that since I was a kid but I'm only 31 fucking years old... surely I don't have old lady version arthritis....

Could this be anything else that any of you are aware of? I'ma go to the dr eventually but it's gonna be awhile because 1.. i have to work everyday and 2.... the clinic i go to takes like a month to get you in if it's not an emergency....
But it's really bothering me....
Any suggestions?
