RA used to be much worse. They make "biologics" now that pretty much prevent the joint damage that used to make hands virtually unusable absent surgery. But these biologics are a lot like the mRNA vaccines - new and high tech and who the hell knows what it does at the molecular body level. The stuff I take was considered experimental when I started it. Warning label was 4 feet (FEET) by three feet. Both sides. Fine print. But it worked - took from me immobile to golf in days. Now they have a lot of them - according to the commercials and Phil Mickelson. So deciding to take a Covid shot was a no-brainer after taking this stuff for the last decade. If chemicals are gonna eat me from the inside, I'm already a goner.
