Unfortunately, Yes.. Some days my knuckles hurt I cannot wear my rings and if I bang my knuckles the pain is intense. Then they settle down and don't hurt so much. Hope you find a way to ease your pain..

Sometimes when my finger swells, I have either overused day before or slept on it wrong, or with RA, it just happens. My remedy : I sleep with a soft splint + NSAID(advil) /tylenol. Then in am, I heat and slow ROM activity. If not better 24-48, I call my doc.
I've had 7 hand/wrist surgeries including fusion, tendon reconstruction and bone excision. I have a collection of hand and wrist devices/splints/wraps, I always look at drug stores and medical supply stores for variations.

I have used it in the past on my back, foot, hands. I will give it another try

Left knee was done 14 months ago. Healed beautifully but still stiff. Right knee will have to wait until after my back surgery. That’ll be late summer. If I can build up some courage. Except the inflammation, that’s mot RA. It’s OA & stenosis complicated by scoliosis. Causing instability and pain and mobility issues.
Ugh.

Which knee? both? I taught myself to drive with my left foot, (had 3 foot surgeries too) and also write with both hands (ruptured 4 tendons dominant hand) . When you're on a safe road with no traffic, practice braking and accelerating with left foot .
