As others have said, sounds like a pulley issue. I've had a couple of tweaks lately, and what's worked for me is:
1 week rest, if there's any inflammation or if it's sore to touch the area then it's too early to climb
2 weeks light climbing. Slopers and pinches are fine. Don't pull anything with a closed hand, even a jug - I use tape so I can't bend the finger. Load each grip slowly and carefully.
2 - 4 weeks of progressive increase. Listen to your body and stay away from crimps and dynos. Don't rush because a setback will send you back to step 1.
