This is a bit weird, but I started getting mild wrist pain from computer use in college, and I credit two things with reversing it. One was rock climbing which strengthened my forearms and wrists, and the other was developing a habit of cracking my wrist joints. I stopped rock climbing many years ago but I continue to crack my wrists to this day. The habit causes me to flex and stretch my wrists every so often while…
I tried painkiller cream (don't think it helped), wrist brace (pretty much impossible to use mouse with it), wrist exercises (bending/stretching arm) didn't help.
I switched from traditional mouse (HP 255 dual wireless) to my wife's Logitech Lift Vertical (she didn't use and bought based on my recommendation anyway, so replaced with my HP) and the pain/issues were gone in ~2 weeks, not sure if it was thanks to the vertical mouse or if it would gone by itself, but just to be safe I keep using vertical mouse. Later I went to preventive check with my kid to their pediatrician, amusingly noticed he is using exactly same mouse.
Btw. how do you crack your wrist (you mean sudden movement to left/right/up/down)? I crack finger joints, but would never think of cracking the wrist.
