I haven't had problems with my wrist, however I have had with my shoulders as I am fairly large my arms are even further out than many causing the bend back of the wrist onto a traditional keyboard to be problematic. It's the same problem as causing wrist issues for many but I found the impact on my shoulders greater in my case.

Though excited by a number of custom ergonomic keyboard designs (a la ergodox etc), I started using the Microsoft Ergonomic keyboards about 2y ago, specifically the Sculpt Ergonomic and later the Surface Ergonomic. That has helped my comfort in that area a lot - and had a relatively low entry price ($100-200 AUD) versus some of the crazier keyboards. I would highly recommend them. The sculpt ergonomic (older version) also had a front rest to raise it to a kind of back angle. The newer Surface Ergonomic does not have that which I miss, but it does have proper arrow keys, home/end/pgup/pgdown and function keys. It also has a number pad which I dislike as it puts my trackpad further to the right, the original Sculpt did not. Either way both of them were a huge improvement and I would recommend either.

Secondarily laptops are DREADFUL for posture, because the screen is very low and the keyboard often quite deep into the desk. I've found this causes both slouching of myself to get to the keyboard and then my neck to look at the monitor. So I gave up using a laptop and now use a desktop - though a keyboard & mouse for your laptop is also a perfectly good solution! I have my monitors raised up off the desk about 10-15cm more than the default stands would allow (even a Dell fancy pants one) and find that is the best comfort for me. There are also various guides online for how to best setup your keyboard & monitor position, relatively also to your chair position. Arm angles etc. I'd suggest finding an authoritative guide and following that.

I also use a trackpad - but not because of wrist issues - I have no idea if that would help or hinder wrist issues (Google might know?). But from using a Mac Laptop with a very good trackpad for many years, I much prefer them to mice (actually I really dislike Mice) and so now I use a Logitech T650 trackpad on my desktop.

I would really like to move to a standing desk but I am a bit prohibited on cost for that one right now. I need to save a little as I think its a worthwild investment - but I think I want a desk that raises and lowers the entire thing as opposed to the vari-desk style systems - partly related to the fact I have 3x24-27" monitors. But it also needs to be fast & quiet.. mmm.... next project.

Lastly I would feel remiss not to refer you to your GP or some other kind of specialist in this area. There are serious problems that can occur and require treatment (a la Carpal Tunnel). You can read all the opinions you like but I was never having real pain of any kind personally, just a bit of discomfort. I decided to tweak my setup for the better. If you're already into the area of pain, having someone look at it and potentially do some scans etc seems like a highly valuable investment into both y
our working future and your personal comfort - I am fairly sure these issues can escalate if untreated. Your hands are valuable.. don't mess around and at least investig
ate it with professional help!
