I once magaged to pull a terrifyingly long fish bone from out the side of my finger. No idea how it got there and even less idea why I wasn't in agony before the discovery.
Gah Prue - that is incredible and horrible. A trail blazer and all.
Not sure whether to recommend that you shouldn't run or you shouldn't sew! I used to use a swiss ball at my sewing machine - you live in fear of dropped pins.
Based on my experiences, sewing is probably the more dangerous activity.
