The first thing to do is to stop climbing instantly. If you can’t see a doctor immediately, assess your finger for the next few days to determine how severe the injury is. In the meantime, combine cold therapy with gentle finger workouts for the finger that hurts.
The first three days are critical in terms of icing, and you’re supposed to continue icing whenever you feel pain. Furthermore, if there is brushing or the finger joint is unstable, you should visit a doctor.
All the same, if there is no brushing but no improvement, you should see a doctor. The physician might do an MRI to find the issue and will afterward create a treatment plan.
When it comes to recovery periods, they will vary depending on the seriousness, though 4 to 6 weeks is the standard time. Once you heal and are okay to climb, begin with the easy problems, and progress from there.
