In addition to desk ergonomics: * See a physio for the elbow, do all the exercises they prescribe. * Get up and walk often (get a drink of water for example).

In addition to desk ergonomics: * See a physio for the elbow, do all the exercises they prescribe. * Get up and walk often (get a drink of water for example). * Walk as much as you can outside of the working day, at lunchtime etc. * Stand up as much as possible, e.g. at meetings, on the train/bus, to counteract the sitting. Sit/stand desk might help if you can have one. * This probably wont apply, but consider if you need reading glasses to help you see the screen without leaning in.
