Both Ben & I have had to do some serious adjusting to the way our offices are setup. Ben actually went to the emergency a few years back suffering from shoulder issues and had to retrain himself over the next few months while in therapy, so as to put less stress on his shoulders and neck.

Now we both have proper office chairs, keyboard trays that are at the right level, lifts for our laptops to bring the screen upto the proper level, etc. It took a while to get things setup right, but its made a world of difference. And I can tell whenever I am sitting at a non-ergonomical desk as I am very sore the next day.

We haven't done the stand-up desk, actually this is the first time I have heard of it. Although I think I will pass on it as I am comfy the way things are now.
