Is it Ice pick headache?

Well, you've not only described the spike effect of the headache, but also head pressure, vision blurring, some tension, facial numbness, hearing changes. As long as you're not looking for a diagnosis, I'm going to propose that there may be a neck muscle as a problem. You've mentioned a lot, and I'm going to try to tie them all together. So let me tell you a story, and you decide if it applies to you. I'm going to suggest the possibility of a particular muscle being tight, one that attaches to your collarbone and sternum. When you read about it, you'll see why I say it. The muscle isn't really suited for direct massage, because if the Vagus Nerve is pressed too hard, it will cause the heart to be slowed, or stopped for a bit. There's some anxiety on what the problem might be, I hope I can help.

The muscle is the Sternocleidomastoid. First site shows its location, also some symptom sites. Notice that the sites are all over the area, including multiple locations at the head and the neck. If you're not having all those other symptoms, count yourself as fortunate. Second site tells more about Sternocleidomastoid Syndrome, with more listed symptoms. This is what you may possibly have with what you tried to describe. The site talks about locations of problems, even including a lump in the throat, quoting here "The pain referral pattern of the SCM includes pain over the cheekbone, in the forehead, on top of the head, in and behind the ear, over the chin, over the SC joint, over the forehead, and deep in the throat. The throat referral is a commonly overlooked cause of sore throat, often mistaken for pharyngitis. The patient will often feel a fullness in the throat, especially upon swallowing, which feels like a partial obstruction."

Isn't it neat that one muscle in trouble can cause such symptoms? Any of the rest sound familiar? But it doesn't HAVE to be painful. Like when it discusses vision blurring, hearing loss, dizziness, vertigo, etc. Notice it even mentioning "reversible tinnitis". You can read the rest. Anything you don't recognise, look up the word. Notice that it can even cause a feeling of fullness in the maxillary sinus. A person could go through a load of decongestants without relief, because there wasn't REALLY congestion from allergies, just from a tight muscle.

There's also "lacrimation". That means that the tight neck muscle can cause an eye to be pouring out tears. How interesting that one neck muscle could cause all that and more.

How to find out if this could apply to you? That's an easy one. Stretch it. With a special stretch, and the next two sites tell you how to do it. And if there is any difficulty in either direction, work to it slowly and gently, because you'll know you're getting closer to getting it resolved, and may have found what's causing the problems. And be sure to alternate directions for the stretches, since doing it to the left is stretching the one on the right, and I expect that there is need for stretching both of them to be sure to deal with, and to prevent the other issues you haven't gotten, or didn't attribute to a tight neck muscle. Be sure to include the upturned head portion of the stretches.
