I’d been wondering why I was getting pain in my right shoulder recently.
Nothing sharp, just a dull ache by the end of the day.
I realised (by accident) that it was the height of my standing desk.
I’d bumped the height switch a few days prior and the height had gone from 84 up to 85. And in the following days the shoulder pain started.
I took it back down to 84 (ie 1cm lower), and the pain stopped after a day or so.
It’s perhaps surprising that such a simple thing as the height of your desk can make such an impact. But in hindsight it makes total sense. It affects the way your hands rest on the table, and how they interact when typing. And it moves the impact up your arm until it has no where else to go but to hit your shoulder and lower neck.
Lesson learned.
