In reply to lucas95:
What I'd do is:
Rest until you have full mobility back, this may take anywhere from a week to a month depending on the severity of the injury.
Come back very gently into climbing. Tendons and ligaments do not like change. Measure progress in weeks, keeping in mind that "easier" bolder problems in the region of V3, V4 can actually be very stressfull on the fingers if they are crimpy.
I don't think there's any scientific evidence that taping is effective, however I put quite a lot of tape around the finger to make sure that I can't fully crimp and also to remind me that it is actually still injured.
In the process, it might be worth modifying further your technique to be less reliable on full crimps with careful footwork and use of a half crimp and fully openhanded grip. Dave Macleod writes a great deal about this in both of his books.
In the process also, try not to get depressed if you miss too much climbing! In January I came back to climbing after tearing a ligament almost completely in September. It took me two months of having fun on easier stuff and recruiting strength and technique back to get where I was before. In fact, just did a personal best at the wall and feel stronger than before the injury and with more understanding of how to train and push.
Happy healing and enjoy the free time you get from climbing in the meantime, hope it's a minor tweak that takes a week or so! :p
