welcome.
there is a site for occipital neuragias on here so it will be worth you looking in.
i have o.t take tegretol, gabapentin 1800mgs, methadone, amytryptaline & nerve blocks of aneastic & steroids. at the moment am having a breather from blocks & using versitis patches which are difficult to stick on head & face
i`m just getting used to them but so far pain no different maybe early days i`m hoping so.
all the best & take care
jane
