For quite a while now, but until recently, just occasionally I would get a pain in my forehead just on the left side when lowering my head to look down towards my feet. It’s almost like it starts from the click in my neck. It’s got more frequent lately and tends to bother me most first thing in the morning when I’m just up. It goes as soon as I lift my head.
i suppose one answer is don’t look down!
I’ve tried “Dr” Google and can’t find anything, sinister or otherwise, so wonder if it might be another weird MS thing.
