I'm sorry to hear about your diagnosis and your symptoms. I'm glad that you found this community and are joining the conversation. We cover a lot of topics here about everyday living with MS with people who "get it."
Below is a link to an article that is about shaking as a symptom of MS. It references the head, so I thought it might be of interest to you. And there's an discussion with fellow members in the comment section of the article, so be sure to check that out as well.

And of course, it's always important to loop your doctor in on any new symptoms. If you haven't done so already, I would likely be worth calling your doctor or sending a message through a patient to get their take on it.
Thanks again for posting and sparking this important discussion.
Best
