I take it the pain returned? I take it the doctor didn't mention anything about occipital nerve blocks or injections? Since they feel that is where the pain is coming from, a lot of times they can do injections in the nerve to see if it helps. You can read up on that if it still bothers you. I tried on 3 months ago and it helped a little, but my pain also is farther in my neck too and finally was also diagnosed with cervical facet syndrome. I was supposed to start the same medicine you are on, but am wanting to get off medicines and hoping for other injection options. Waiting to get back into doctor.
I too have used heat. I was given a gift called a Bed Buddy. It is basically like rice in a sock type thing, but already made up. I've seen them at Walmart & Walgreens before. I also love a good size gel ice pad that will fit on the base of my skull nice.
Keep us posted how the medicine works for you.
Best wishes,
Denise
