Orange,
ugh, thats not good
I did a lot of research when mine happened, basically surgery is a last resort and something you only want to pursue if its the absolute worst case in terms of injury (a complete severing of the pulleys). Unless you completely severed the pulley it will grow back together on its own, and really there isnt anything else than can be done. It should be obvious if you completely severed the pulleys because you will have whats called "bowstringing". Basically the tendon is attached at the tip of the finger and then down in the forearm, and the pulleys are what hold it next to the bone when you bend it. So if the pulley is completely gone when you bend your finger, the tendon wont stay next to the bone (since the pulley isnt there to hold it in place) so your finger will look kind of like the side profile of a bow and arrow.
The vast majority of climbing tendon injuries arent severs tho, and pretty much every climber who climbs long enough will eventually **** a tendon up and go through what you are going through. So just from the odds you are prolly going to be ok long term, its just going to take forever to heal.
Basically the absolute best thing you can do is rest it, no climbing at all is best, but if you are going to climb, absolutely do not do anything crimpy!! Nothing but easy open hand holds (ie, jugs). You can also frequently massage it, and work on stretching. Supposedly laser therapy can be helpful, but I dont really know much about that.
Taping helps, but really the biggest benefit of taping is just to limit the mobility of the finger and to remind you that you are injured and not to push it. Its pretty much impossible to use the tape to replace or fortify the pulley, as youd have to make it so tight that it would cut off circulation to your finger.
I tried to use my time off as a positive. I worked on other aspects of my fitness that would help my climbing that I didnt necessarily put the time into while climbing. So I did a ton of pullups, and worked on strengthening my other upper body muscles. Also when I was busy climbing easy jugs, I really really focused on using good footwork, since my (and most every climbers) foot technique was pretty sloppy.
Also drink a **** ton of water. Water is like lube for your tendons, and tendon injuries are more likely to happen when you are dehydrated.
Its a lot like being in a downswing in poker, when its going on you dont ever think it will end, or that youll ever be back to where you were again, but just like poker it will pass. Like I said, it took me really 9 months to fully recover, but Im climbing stronger now than I ever have, so just dont make it worse by pushing it and you should be ok.
