Jeff’s reply was good. If you’ve read my first posting in this thread, there are a ton of suggestions for putting attention (and thus energy) into the ground (“lower down” isn’t quite as helpful as, like, Earth). Stomping feet isn’t one of them. Have you tried any of my suggestions?
That indicates to me that there may be a physical problem involved. Most of the blocks yoga dissolves are created by infinitesimal actions repeated over the course of many years (think Grand Canyon/Colorado River). You can open them, but the block will return over the long run if you cease yoga practice and fall back into the same unconscious patterns.
But if it’s snapping back next day, it’s not the aggregation of feathery infinitesimal actions, there’s something way more macro and physical happening here, and I think your idea of craniosacral therapy is a good one. I’d encourage you, though, to mentally separate two issues. There’s the block, and there’s the feeling of energy pooling behind the block.
Lots of healers know about blocks. Blocks, by one name or another, are what many (perhaps most) therapeutic efforts are directed toward. The energy issues which are made worse by the block are not directly part of that problem, they’re more of a secondary consequence. So I wouldn’t complicate the issue by discussing them. Don’t talk about the energy, talk about the feeling of blockage (really, they’re two sides of the same coin; we don’t notice blockage unless SOMETHING’S trying to flow past). That will be much more understandable and addressable by your healer. I’ve found that outlining a whole grand story about kundalini flows and overloads and stuff just over-complicates, and either confuses healers or excites them and makes them want to add more energy to your system. Any healer who feels comfortable dropping the word “kundalini” is probably - regardless of what they SAY they do - going to add energy, and worsen problems. There’s no science of SUBTRACTING kundalini. That’s not a thing.
So focus on blockage, both in how you monitor the treatment, and in how you discuss the condition with the therapist. After ten years of kundalini, I can honestly say that there’s never been a good reason for or a good result from discussing my kundalini with anyone ever…except to compare notes with fellow yogis.
If I was suggesting you move your Adam’s apple down, or moving anything else, I’d have said so. What I’m suggesting is an energetic action, not a physical one. And while I realize that’s something most people find difficult to conceive and do, the fact that it’s something you’ve previously learned to do with your ear canals makes it possible to transfer that know-how to the throat.
Reread what I wrote. Don’t just sail through, pay close attention. I’m not doing a sloppy job of telling you how to do something concrete, I’m doing a careful job of telling you how to do something hazy! 
And if I seem a bit wacky here, it’s all my energy doing it I promise! LOL, but likely is my damn heart again, making progress. Gotta do something about that…
