"If so, what should I be using and how often?"
Yes, do both internal and external high CBDs. The CBD dominant topicals applied every hour during the waking hours to the base of the skull and the first 3 to 4 vertebra and do oral CBDs in addition 2-4 x/d in a tincture, tablet, lozenge or vape solution and you should be able to make a huge reduction in the pain level within 1 week and the pain may not return with continued use. Good luck but you may need to eliminate any neurotoxin exposures.
