Honestly I would not let anyone other than a professional touch your neck, not even a soft massage.

I have awful neck problems so know how you feel, my pain also goes in to my left arm/fingers. Just small things can flare everything up.

I have a cervical collar but don't wear it unless I'm in terrible pain and the physiatrist said to only use it short term. It really helps.

Epsom baths are good, sometimes they help my neck, other times they don't but worth a try.

Special neck pillows are a life saver too, I can't use just a normal pillow.

Hope you get relief really soon, it hurts so much.
