Neurological term for a symptom

This is based on something I have (because it's easy to write what I know), but I'm going to sound like an eejit and not know what it's called.

I have a neurological disease that progressed to a point before Dx and treatment. Once things worked, we didn't delve into terms for things. The disease is Subacute Combined Degeneration of the Spinal Cord. I'm on B12 for life, totally fine and all that. No worries about the remaining symptoms, other than how they are annoying and things, obviously

The symptom that I know nothing medically about is a shaky head. Nobody can see it, but I can feel it, and it's irritating. Often, I literally hold my head still so that I don't feel it and that does work for the most part. It's like my head tries to move on its own, very slightly but it feels fairly forceful. It's not a sensation I can make happen consciously or mimic. It's worse when I'm tired.

I have something called an 'intention tremor' on the touch-your-nose test. This may be called that, too? I just don't know the terms. IRL that works fine, but I don't want to sound like an eejit as an author My character would know what it's called.

Thanks!

Oh! And another one, if you're on a roll. I'm not sure I'll use this one, but there's an eye thing. If my eyes are tired, they go back and forth super fast. Not many times in a spell (like once), but fairly often when I'm tired. Folks have seen that one (much laughter cos it's pretty crazy looking, apparently ). I've told the docs, of course, but again I have no terms for these things

You're good! Thank you

Thank you, Kenn and cornetto! It does sound like nystagmus. I'd wait for my next appointment rather than call, because those folks are slammed with patients (it's a specialty pain clinic, while our regular docs in the area basically refuse to treat certain things). It's not important in the scheme of things

Thanks!

Thank y'all so much! I know that the technical terms may not make any sense to the reader, but I wanted to know them so I know my options.

Nystagmus should do. I have no idea what it really looks like on me, just what it feels like It feels like a fast back-and-forth, but I'll try to notice if it's just fast one way. How interesting. It happens very quickly.

These things are happening, and neurologists can see things other folks don't notice. I just mean the head thing is not noticeable to people in the room with me, or anything. It doesn't resemble Michael Fox, etc, for instance.

You can bring on nystagmus by squirting ice water on the ear drum. I do that from time to time to test a patient's brain stem function.

Why do I see that as a good drunken party trick, bwahaha?!

That's fascinating. Thank you! Does it bring on nystagmus in everyone?

Fenika, that's an excellent link. Thank you!
