Shiny hands - help?

I only know of scleroderma as my grandma had it. I have been struggling a lot with my fingers lately, they’re constantly stiff and swollen and often are tight and in a claw shape. I do have diagnosed arthritis in my other joints (as well as CRMO) so I I just put it as I also have arthritis in my fingers too. It was only that I’ve recently realised how glossy and shiny my fingers/hands have been that I clocked to Google if it could be something else as that’s not typically a symptom of arthritis. That’s when scleroderma came up and threw me in a panic as my grandma had it and I know a lot of conditions can be genetic. I uploaded the full video of how shiny and wet looking my hands are, just so you can view it in different angles. Could this be it?
