Sudden pressure in ears and back of head, stinging sensation at the base of my skull

So, like the title says, I've been getting this random pressure in my ears out of nowhere... like they're clogged, plus this intense pressure in the back of my head and some stinging or tingling sensations behind my ears and above my neck. It only lasts a second or two, but it totally freaks me out because I'm worried it might be something neurological.
I actually have some issues with my cervical spine, so I'm wondering if that could be causing it or if it's something else entirely?
