I have occipital neuralgia and severe arthritis in my neck. The doctor prescribed baclofen, a muscle relaxant, especially for the neck. I was given some stretches and other exercises to do. I use a shiatsu massager everyday, a heating pad and red light treatments.
I made an oil - jojoba and peppermint oil and rub it on my neck before I go to bed. The cooling distraction of the mint provides some relief and distraction from the pain in my neck. I use a special cervical pillow and sleep on my back.
Maybe it would be good to follow up with your PCP and see what other therapies would work for you.
