I have the same right ear to neck pain which I associate with PMR pain.
I have lessened it with a pain ointment compound originally prescribed for my knees.

I also lie on my back with an ice pack under my neck around 6:00 pm after supper when my neck and shoulders pain peeks (?!) Relief is
very rapid.

At my (early) bedtime (7-8:00) I take
a tiny dose (5mg) of THC and CBD both legal in Alaska. They quickly induce a deep sleep between brief urination wake-ups.

Prednisone 4mg down from 20mg
6 years ago. No real remissions!
Too much induced bad dreams and
can lead to psychotic thinking.

I’m up at 5:30 in my assisted living
home. I’m 88 ( 38 above the neck and 108 below the neck)😇👍🌹

Anyone with luck in Eastern medicine out there
