Small bump on ring finger… anyone know?

Thought maybe someone here might know 🤔

So for around 10-ish years I’ve had this little bump on my ring finger on my right hand. Its in the middle knuckle joint on my palm side.

Its never really hurt or bothered me, and I’m able to very very slightly move it, but not much at all.

Since it’s never hurt I’ve never thought to ask a doctor about it at any point.

Well I noticed today that the joint below that (where my finger connects to my hand) has felt a little sore whenever I push on it or hold something, also on the palm side.

Well I noticed that I also have another little bump there now, and that one is very easy to move. I’m not sure exactly how long it’s been there but not nearly as long as the other one, ive just noticed it today when I noticed that joint was a bit sore.

There’s been a couple of times that I’ve tried looking up what it might be but I can never find anything that really fits the description.

Just thought maybe I’d see if anyone has had anything similar or any idea what it might be! Thanks!
