go to
www.rockclimbing.com and search through the injuries and accident forum to see if you can relate your injury to someone elses.also post your question in that forum but you will have to give a much better description of what hurts,where it hurts,what motions cause pain,WHICH FINGER IT IS THAT HURTS! etc otherwise people will not help you.google the hand/finger/forearm anatomy aswell to brush up on your knowledge of the various mechanics of the hand/finger etc.tingling and numbness are symptoms of nerve injuries but you more than likely strained a flexor tendon(there are different flexor tendons,it depends which finger you hurt).something you can try in the meantime(ONLY ONCE) is to hold:
1)hold your arm out straight(parrallel to the floor),palm facing down
2)flex your wrist sothat your finger tips point towards the ground
3)bend only your injured finger towards you,keeping it straight
if you strained that finger flexor tendon this will cause pain up that tendon in your forearm.
another important thing to state is whether you were close crimping or open handing that 3 finger pocket.i pressume you were open handing which would tend one to head more towards a flexor strain.
DONT play around with that finger(bending it and testing it all the time to see if it still hurts cause that will just prolong recovery)
dont waste your money going to a general gp,if anything go see a orthopedic hand surgeon
good luck
