No-one has offered an explanation of why a number of people have observed
joint pain. Joint conductivity is speculative.
Or why there are therapeutic currents used in a variety of devices from DC
up to at least 27 MHz with benefits in pain.
Many of these such as the TENS machine use a more sustained total delivered
current over hours.
A VHF field is different and heating may be significant compared to trivial
power from a TC into a 50 ohm load
In fact, electrical currents have been used to stimulate bone growth.
So why does a tolerable Tesla coil shock cause a problem?
I have never had an intentional or accidental shock from anything larger
than a 3 inch weak spark from my briefcase Tesla coil so I can't comment
from experience.
Are we really dealing with much higher peak currents?
So what is a tolerable Tesla coil peak current?

Subject: Re: [TCML] Joint pains with Tesla contact ?Myth
While playing with small to medium coils holding an ungrounded metal rod
to draw the arcs, I have always found the pain to be in my wrist (not
necessarily the joint).
I assumed this to be to the increased current density due to the smaller
cross section of conductor...?

Joint pain (wrists and ankles) observed after exposure to high Rf
fields, notably in VHF range, surmised to be for the reasons Antonio
describes.
