I have OA in my neck with trapped nerves there also, I'm usually in a lot of pain. In do stretches everyday that help some but recently I have started to drink two cups of Turmeric tea per day and now I am almost pain free, it's amazing.
I researched about it before I used it and it turns out that it helps a lot of people with their pain, it's a natural pain killer.
One thing negative that I read is it can't be taken I you are on medicines for blood thinning, wharpharin etc.
It might be worth a try for some of you.
