Can this networks wisdom help me out?

Yesterday I ended up with a small splinter of metal (from a screw) in the tip of my index finger. No worries, I figured it'll come out by itself.

This morning, turning on the tea kettle, I felt a faint buzzing sensation. Not painful, but not pleasant either.

After some experimenting it seems to be the metal splinter reaction to (very) nearby electric fields (transformers etc).

Is this some type of parasitic capacitance?
