I went through something similar for many years. I went to physical therapy, I stopped running, I bought a StandDesk, my wife bought us a new bed, I almost stopped drinking wine. It lasted for years. None of those things worked.

Unbelievably what worked is what 3 people have already mentioned in the comments here already...

I started taking a vitamin daily.

Hard to believe, but I've been fine for a year.

This is the vitamin (I am not affiliated with this company):
