It's funny, I've had this for years and I'm almost certain that it's related to my optical migraines, as this is where any pressure I feel during them emanates from. However, my chiro suggested last week that it might be related to the spur (or whatever it's called) at C4/5. Referred pain. She might have something there, but this has been going on for so long and it's definitely in the occiputal area, not further down.
It doesn't actually cause headaches that I can tell. It's localized to that one spot. It's just always there, no matter what intensity it is. Sometimes, very rarely, it goes away completely for a few minutes, which is freaky because I think something's wrong when it disappears like that!

Very weird.
I never even thought to ask for specific pain relief for it. Hmmm. I do have nights when it doesn't matter how I lie, whatever side, I cannot get comfortable. The pressure on that spot is awful at those times. I just try to breathe and find a way of lying that's less uncomfortable.
I'll ask my rheumy about that when next I see him. Thanks!
Warm hugs,
