I can say from experience that one can get internal burns and that it takes
a while for the pain to develop. I used to this sort of thing a lot in my
younger days before the internet when I didn't know better. Now I would
never do such a thing. One time in particular I had the joint pain described
and it was several days before it went away entirely. Not a good idea.
BTW, you can light up bulbs without touching the discharge.

The high-frequency current, from a Tesla coil is not sensed by the nerves.
Not harmed at all
is not exactly the case. Burns can occur, external and -internal- as the
current breaks the skin
and travels through the body. Skin effect, that makes high-frequency
currents travel close to
the surface of conductors is almost insignificant at Tesla coil
frequencies with the human
flesh as conductor. A common effect is pain at the joints, because there
the resistance is
higher and most damage occurs. Even staying close to a Tesla coil in
operation can cause this
(to me at least...).
