Any motions to avoid with arthritic hand?

(Ok, guys, this is in General, so never mind all those hand movements you might want to suggest.)

I broke my right wrist 5 years ago. Some of you may remember my spectacularly awful typing during that time. My doctor told me that I’d be having trouble with arthritis in that hand later on, and here it comes—stiffness and discomfort in the right hand, making it hard to write and draw and do other fine-motor things. My grip is weak and I often drop things. I have to correct an awful lot of typing errors, mainly missed letters. This has come on just over the past six months.

I can still easily do all the exercises shown here on the Mayo Clinic website, so it’s not too bad yet, but it’s progressing.

My questions:

Do you have experience with this? Do those exercises actually help? Can they prevent or slow the worsening effects?

And is there anything I should avoid doing because it’ll make things worse?

Thank you.
