re: Admitting our dangerous (and dumb) mistakes might help others.

Easiest way to relieve pressure on a nail bed (like on the hand, not the kind that holds wood together) that is swollen is to open a paper clip, heat the end to red hot and touch the nail. For that procedure, I charged $80 (+ paper clip) (just kidding about the cost ;-)
Only do this if there is blood under the nail… that will be 5 cents please.
