I don’t use it personally, nor do I have arthritis, so I can’t give a first hand account on effectiveness- but I know of multiple folks in a similar scenario that have found relief with CBD and/or THC. Topical cream seems to be the favorite- relief where you need it without any cognitive effects.
This is what we finally did for my 94 year old grandma. We took her to ten different arthritis doctors, nothing worked. She's just old and hurts. Got her an rx and a THC oinment thing, looks like a big tube of chapstick, and it keeps her from hurting with no side effects we notice.
