Good posture is also important. Eg when leaning on the back, the tail bone should be the part that is touching the back of the chair, and the upper part of the back is barely touching, or even away from the chair. Although I learnt this, it is hard to be always doing that, because bad posture (just causally leaning) feels better at the moment, but in the long run a good posture make you less pain. Also consider invest in split keyboard and vertical mouse. I have carpal tunnel syndrome and it is a must for me. But the fact that such a set up makes people like me painless means that it is the most neutral position for your hand. In general, avoid any tensions. In the neck, or foot, etc. when you are deeply focusing on a problem, try from time to time focus on your body instead and feel if there’s any tension. They are the things that’s killing you in the long run. (Disclaimer: Not a doctor, just a fellow painful person most part of my body.)
