oooh, you guys - don't do the duct tape thing. Most GPs have a zapper, guess it freezes the tag, the tag gets all crusty and scabby, and then falls off on its own after a few days. It's painless after the initial freeze sensation.

I had it done to one that was under my arm pit. It's really routine these days.
(those little tag things are SO weird) Doc said if I ever could find the cause of 'em I'd be a rich woman. Let's put our heads together, if it's a side effect of medication, let's tell them so and lay claim to the cash prize.
