In reply to mathesar:
How to start, I've been climbing for almost 10 years now. The second year I had a full A2 pulley rupture. Bummer.
Same dilemma as you. After reading endless sources and taking advice from different people including doctors, friends and climbers... I came up with a hand doctor that was specialized in rock climbing injuries.
He basically told me:
Only go to surgery if you had a multiple pulley rupture and your finger is mechanically affected. That is, you can't bend it at all , you can see tendon bowstring and there is no way your body will be able to recover by itself. Unless you are a professional climber that has access to high skilled surgeons and proven recovery treatments on rock climbers in the past, don't do it.
Thing is the hand, is one of the most complex mechanical systems in our body. You screw it... and the consequences can be very bad.
On the other hand the conservative treatment is actually very effective. I rested for 3 months... yes I know... is a bit of a bummer. Look for other activities, running, cycling, etc. Then started to climb slowly. In 6 months I was climbing at 70 to 80 % of my capacity before my injury. 1 year later I was fully recovered.
The forth year of my short climbing career I had the same on my other hand. Damn it! Did the same thing...
Today I'm way more careful than I used to be... I understand my body much more and have less injuries. I don't go to the absolute limit any more though.
Hope it helps and good luck with whatever you decide to do.
Cheers
