OK so an acute, although it seems to have gone beyond that to me, or it is within range of a sub acute, lingering acute, almost chronic (typical of what some call viruses, the sx often lingering and merging into a more long term illness). I think I would be tempted to go with the chronic because I can't but help think that the ongoing TMJ is linked to what she has now and also all these other sx as well, but I can sort of see your option - a nbws a cold and a possible ear infection, which is why I suggested you check her sinuses with the ear problems, there could still be infection. Have you checked inside her ears, looking for inflammation.
Doesn't matter what you call it Vestibular Neuritis, Meniere's is similar, TMJ, they are just names that suggest a whole range of sx and you obviously need her individual ones, covering the vertigo, ears, the original cold (might be a lot of useful sx from then), any hearing changes, discharges (you mentioned sticky?), pains, modalities - the usual thing.
Nux vom is hardly 'laid back' though. Seems quite closed to me and there's all this anxiety underneath. Have mentioned Bryonia and Manganum especially as rx but not sure you've got the whole case here to make other suggestions. Could be a connection to dental work/fillings as an afterthought, seeing as you mention it

Re: Lizard
I do have the whole case but because of the way I started off I have only posted in bits 
There is definitely something going on here as to my question how long has she had all this stiffness she answered:-
"I've had stiffness in my legs on & off for a long time, my left hip is worse than the right. Its usually when I'm cold or can be around my period. I get a "toothache" pain down my legs - I feel as though its in my lower back, around my hip & groin, in my knee then into my feet. It can be quite bad for a few days at a time & then its more of an awareness than pain but its pain at the minute - probably because its damp & cold."
Rhod????? But I feel I need to sort the dizziness stuff out first as that is what she came with.
