>>9691093Update: anyway I kinda did some self-surgery, opening in the tweezers would channel a bit, exploring the wound with a high-powered loupe and watchmaking tools, and scraped out all the H-18 I could (all the while flooding everything with generous amounts of alcohol of course). There's still some black metallic shit down there, but I can't reach it. At least my finger immediately hurts less, so I guess partial success.
The rest I'll just have to wait for whatever. What now? Will it get dissolved or pushed out or something?
