iontophoresis question

[ultrafrost]

hey, I recently restarted my iontophoresis therapy, but this time I found that the hand on the positive polarity would feel more tinglings than the other polarity, is it normal? when I did the therapy in the past, the hand in negative polarity would have more feeling. I don't know why. how about your treament?

ps: I use stainless steel pans as electrode this time. in the past, I use aluminium plates.

thanks so much

Usually the tingling is about equal in both my hands, but it can vary depending on how how much my hands are emerged in the water.
