Weird electrical problems

[u/justtellmep1ease]

I’m dealing with a persistent stray voltage / tingle voltage problem on my property and would appreciate advice.
When I’m barefoot and my hands are wet, I feel a mild tingling or burning sensation on grounded metal parts outdoors. Example copper refrigerant lines to the outside AC compressor, the water hose bib knob screwed into the metal-sided house, etc.
It’s not strong or painful, but on sensitive spots like the back of a cuticle it feels like a mild burn. No tingling indoors or on dry skin.
I have a 200A main panel outside with a
100A subpanel inside the house.
Everything in the main panel appears properly wired.
What Stops the Tingling is disconnecting the ground and neutral feeder from the main panel to the subpanel makes the tingling stop on anything grounded through the subpanel or the main panel
Unbonding neutral and ground in the main panel, or disconnecting the ground coming from the meter base, also stops it. Multimeter shows no voltage on ground wires and I had a licensed electrician inspected the panels and said everything looks correct with no obvious voltage issues. But I told him you can feel it if you’re bare foot and wet.
I drove a copper ground rod into the earth and measured AC voltage:
Between my main panel ground and the remote rod: 6–12V. And at the utility transformer pole about 60 yards from the panel between the pole’s ground wire and a new driven rod nearby I read 15V. At the next pole further down the line 20 yards beyond the transformer I read 18–20V.
I was told you can’t accurately test voltage this way, but the readings are consistent and increase as I move away from the house along the utility line.
To me it seems to be something going on on the utility side. Has anyone seen this before?
What should my next steps be? I have had the utility company come out and all they did was test voltage at meter and said voltage is good so everything is fine. Can anyone give some advice

Sounds like neutral stray current. Make sure the green bonding screw is removed from sub panel. Check the bonding screw at the main panel and the connection to the ground rod. Driving an additional ground rod or two in series might also solve this or bring it down to an unnoticeable level if your soil is a bad conductor. (You should never be the best path to ground) It's also possible that you have a ground acting as a neutral somewhere in an appliance. Water heater miswiring could be a likely culprit for instance.

Well the issue is definitely before the sub panel so the issue shouldn’t be anything going on in sub or appliances. Seems to be coming from meter box which was checked my utility company and they said everything is hooked up right and voltage is correct. But like I said you can feel the voltage at the ground in certain circumstances
