so, yesterday i had my first professional electrolysis appointment for a hour, and cleared most of the neck, and next week will probably have most of the area under the chin done.
but i seem to have an issue that im not sure if it will prevent me from continuing, at least, not without issues.
a year or so ago i had knee surgery and have a couple pins and some wires in my knee and i noticed during the appointment that the electrolysis itself didn't hurt very bad, but my knee started getting extremely uncomfortable, maybe it was just from laying in the same position trying not to move for a hour, but cant help but be thinking that maybe there is something going on cause of the metal in that area being affected by the electrolysis.
was constantly tingling, and i had to keep moving my leg and trying to stretch my leg out throughout the appointment.  it wasnt completely unbearable, i think if i had a break halfway to stretch might be better, but if i start doing appointments longer than 1 hr later on, might be even more of an issue.

That's a weird one. Did you mention it to your electrolysist?

she said that it "shouldnt" be affecting my knee, not directly at least.

I think its plausible because people with amalgum fillings in their teeth (including me) feel a metallic taste when having electrolysis.

There could resonance with the AC part of electrolysis (depending on the method).  I don't know if the AC frequency can be adjusted, but it would be worth it to ask.
