I thought I would update those who have been following my problems with my hands. For those who haven’t, my right fingers get very cold, turn white, and then numb when I hold a heavy camera a long time and when I use my computer and the touch pad. My arthritis also causes my hands to get stiff and ache.
My latest attempt to remediate the issue has been to use the Apple mouse, but not exclusively. I switch back and forth between using the touchpad with either my left or right hand and with using the mouse. This seems to help more than anything else I have tried for using my computer, which I do a lot. Using the Fujifilm cameras and prime lenses helps considerably for when I take pictures.
