That does sound horrible. I've had weakness and shakiness too after being in a car/exposed to loudish noise (the two often somewhat come together as just going out involves being in noise, rumbling traffic, loud music in shops and so on - I think both noise and vibrations from movement cause it), at worst I felt I had spasms in my face and neck, shaky weak arms and legs (can hardly pick anything up), and also have a really weak feeling in my jaw, sides of my face, which is disturbing, so that talking or eating is unpleasant. I don't know why this happens but when it occurs it is always after I have been in a car/exposed to noise.
Are you taking any muscle relaxants or anything, I know side effects of non steroid anti inflammatories can be temporary vision problems. I have the shaky feeling however when on no medication at all
Do other people have the weakness and spasms? It is bothersome, the idea of having anything which could be termed a neurological problem is worrying
