Maybe these are nodules? But yes, RA has typical hands conditions and sometimes surgery can be done (if there are any joints left). If joints are pretty much gone, the only thing they can do is what's called bone fusion that will help get risk of inflammation and pain, but also set your finger/s fixed straight for life.
I've shared it in the past, but there an article I've written staring my oun RA hands and explains about those typical conditions. Click below if sounds interesting.

Lol 😂 girl I get it I have bumps on my joints as well

No not unless it inhibits your joint movement so much

It's mainly 1 finger knuckle and only hurts if I bend it hard into a fist 😊

No, it's not bad really... just lumpy looking! Lol
