In reply to RossKirtley: sorry mate but it sounds like you haver done some serious tendon damage to your ring finger tendon , i did this same thing about 4 months ago,short woarm up follwed by a hard problem.
did u hear a popping sound when u came off the wall? if u heard a popping sounds then u probablly have torn/ruptured the tendon,as i did.
there is nothing u can really do but rest xrays wont show anything,you need to ice ice ice everyday 15mins on 15 mins off ,i did this for about 2 months and it greatly helped speed up my recovery,
when u get back into it just take it esy for the first feew weeks jugs etc,i started to boulder again after about 1 month but very easy,if it starts to hurt of twinge stop.but do no let it completely rest and waste away
while u have spare time work on other things ie core strength or cardio,
also avoid deadlifts and pullups with sausages on your back,or u will reinjure yourself,i have great experience in this field
sorry buddy hope this helps
