My wrist started hurting at 26 and I ignored it for four months. Don't be me.
Started as a dull ache after long sessions. I told myself it was posture and kept going. By month four I couldn't hold a coffee cup properly with my right hand, which is when I got scared enough to see someone.
Physio, a few weeks of exercises, nothing permanent. What helped, roughly in order:
- Desk height. My forearms had been angled up at the keyboard for two years. This was most of it.
- Getting up every hour. Not stretching at the desk. Standing up and leaving the room.
- Learning enough keyboard shortcuts to drop the mouse for a lot of things, which made me faster as a side effect.
Nobody in the grind-harder content mentions that your hands are the tooling. The days I didn't get up for six hours are the ones that did it.
