Did some wet diamond grinding with my electric angle grinder (double

If you felt it then you may have bad or mis-wired GFCI.

Note that if the path of current is from hot wire -through you- and
then back to the neutral wire, (not ground) then you will be shocked
all day long.. until the cows come home..... The GFCI does not know
you from a light bulb or any other load.

Just a note. I recently bought some (Leviton I think) GFCI's. They will
not even reset if it's miswired.
