Mine used to be AWFUL. I have this one for anytime I use my mouse...

But I also had to get this one to wear to bed at night or I had a hard time sleeping...

I had to use both braces for years, wrist pads always made things worse for me, I tried several kinds. I haven't used my night one in a year or so, so I must be slightly better or I learned to live with it better
I have more issues with my neck & shoulders these days.
I also tried a keyboard tray for a while which helped but I always hit my knees on it, so with this new desk I left it off & just use a 3 ring binder on my lap with my mouse pad on top, lol...I don't even have to wear my mouse-brace most days doing that, except those days I sit here like 14+ hours...
