Squeezing a Full-Size Keyboard into My Tiny Desk Setup Without Killing My Wrist

I've been trying to upgrade my home office with a full-size mechanical keyboard because I love the feel and the numpad is super handy for work. The only problem? My desk is only 30 inches wide, and adding the keyboard plus my 24-inch monitor feels like a tight squeeze. I tried angling the keyboard diagonally to save space, but my wrist started hurting after an hour, which defeats the whole purpose of the upgrade. I’m thinking about maybe swapping to a tenkeyless keyboard, but then I lose the numpad, which I need for data entry tasks. Desk extenders or keyboard trays might work, but my desk is against a wall on one side and a filing cabinet on the other, so space is really limited. Has anyone dealt with fitting a large keyboard into a super compact desk setup without sacrificing comfort? Also, what are some ergonomic tweaks or accessories that actually help when you’re forced into a cramped desk space? My wrist pain is real, and I want to avoid turning into a keyboard hunchback!
