You can take this as an opportunity to work on bass without the bass. If your living doesn't rely on your ability to play bass of course. You can work without the bass:
- the rhythm, counting on every song you hear or played and discover if you are able to keep the 1 (and find it!), clapping on the one, clapping at quarter or eight, saying different rhythm out loud (if it's not in your head, you'll need luck to play it right every time)
- the melody, sing the bass line, especially on lines you already play and make some correlation between the intervals you sing and what they are (2nd, 3rd, other?), sing the melody of the tune or the second voices to be able to do backup vocals (very appreciated if you want to audition for groups)
- the harmony, learn the chord progressions of the song you play and understand if the bass take always the root or not and why! Discover what you already play with a fresh eye and get more freedom for when you'll be able to play again: you will be more aware of what's coming and therefore be easier on the song (you'll be more relax and less prone to injury too)
There is a zillion things you can work without touching the bass that make you an actual better bass player. Visualisation is also a very good option as it takes a great amount of brain control to imagine the bass and your hands and it mimics in your brain the same work as the one you make when you play.
Keep in mind that if you work the big picture, you will be a better bass player in 3 months even if you can't touch the bass. You only play for 3 years, all the things above can have be less worked than the bass, no?
In between, icing the wrist is a good repair tool.
