Is this a sign of psoriatic arthritis bumps on my hands?

The bump on the middle finger has remained there for as long as I can remember and The last small finger bump I remember developing in my late teens. I have done a MRI on my wrist and no sign of RA activity was noted on my wrist despite my wrist and fingers aching. I am really scared of my ankle spondylitis having developed to my hands and I don’t know what to do with these lumps. I don’t think it can possibly be osteoarthritis either because I would have been way too young to have developed it.

Most notably none of this has caused any stiffness on my fingers. I have trigger finger in both thumbs but that seems to be an inherited issue my mother and grandfather had/have.

I am scared my hands are going to become deformed.
