In reply to partz:
I’m not a Dr or anything to do with the medical trade but I’ve had pulley injuries localised at the base of fingers on both hands (1 on L, 2 on R. This developed at the end of Jan after a lot of training indoors at the same wall doing the same routines.
Have you tried Icing your hand regularly to stimulate recovery (not proven apparently)?
What training were you doing and where?
Are you doing anything different like riding a bike (carpal tunnel syndrome?) or using rings or press up bars to train? Could it have developed in the wrist?
Have you changed something at work?
Have you been to a different rock type or crag, worked a particular crux?
My hands are slowly getting better with almost nil climbing indoors and v little outside and after 8 weeks they’re still easily re-injured. Apparently pulley injuries can cause permanent complications where the appropriate rest and recovery isn’t taken (and I’m 47) so I’d be careful.
I’m trying antagonist rubber finger flexors but too soon to comment on if they work. The joints do feel better after exercise though.
You can try H-taping or taping up the joints to immobilise the fingers so you can keep climbing but it didn’t work for me.
Again I’m no Doc but the old phrase “If it hurts don’t do it “ springs to mind.
Good luck.
Bill (in recovery)
