The best remedy by far and away is plain old everyday dry powder laundry soap. Don't pay attention to brand. Dollar Store cheap stuff is probably the best.
Climb in the shower with a tub of powder (Keep it dry, Dummy) and start scrubbing those little blisters till
they stop itching.
It's not going to be pretty and, Yeah, you're probably going to have to put some ointment on the open
pustules. But at this point you'll do almost anything to stop the itch.
Yes, the relief is immediate! If you know you've been in it just scrub down with the powder....no blisters. NONE!
Then apologize to your wife for not bathing before going to bed and sharing the oils with her. How sweet of you to share?
Now strip the bed of sheets and wash them.
Psst! The laundry soap is in the shower.
