With regard to microshock in the skin..

I haven't heard of such a thing but I did some work on DC current many years ago.

Low levels of DC current usually more than 1mA/square inch can cause quite serious ulcer like burns. Geoff explained the effects of Galvanic current earlier.

DC Electrotherapy machines have been tried in the past and discontinued due to the galvanic effect. This effect, if used carefully can have some clinical benefits and I reviewed a device about 10 years that used an AC wave 'floating on a DC level delivering a mixture of high voltage/low current AC stimulation and low voltage (less than 5V) DC. see: https://www.ebme.co.uk/arts/aps/index.htm
