I suffered from minor shoulder – and wrist pain for a long time. In order to lessen the pain, I decided to train my left hand for using the computer mouse a few years back.
Certainly, using mouse with my left hand was very challenging in the first couple of years. However, 3-year of intensive practice paid me off. I could click, drag, and drop icons using my left hand without noticing that I did so with my left hand.
After having succeeded this “experiment,” I made another decision recently to relieve back pain; standing up while working. I first searched for standing desks or stand-up desks, then read online posts (e.g., reviews by Mark Luckch and Alan Henry), and then created my own standing desk by putting together empty paper boxes.
My DIY practice showed the effect Instantly. I became free from back pain, paid more attention to my tasks, and most importantly, became exhausted at evening as I “exercised” all day long. In short, I was tired at day and slept well at night. Finally, I bought a height-adjustable table from Varidesk. 🙂
