You came here for the problem with the bones.
And I read on what you typed about what the disease is called. Actually what I'd like to know is, can you move any of your limbs at all aside from those spasms happening?
I haven't had the time to reply and maybe someone else knew or wanted to ask you something so thats why this reply is so late.
Also, I simply typed in herbal treatment for dystonia and I came across a website which mentioned Passiflora incarnate, Eschscholtzia californica L and Valeriana officinalis. Now these are sedatives on the nerve system. Im not saying you should randomly try them, a herb does need to fit the person. Not every herb does the exact same thing. Also general nerve strengthening things, herbs or foods or something should help I think. If they're more neutral in property and not like stimulants... Avena sativa is said to be a tonic for the nerves, and calming. Even though it wasn't directly said there in that text.. Actually the seeds are used just like grain or wheat, it can be eaten, cooked like rice in example, or consumed otherwise. Thats why I was thinking of it in general. But I can't tell weather they grow that there or not. I know they do in Europe, or some parts of Europe at least.
Along with meditation in general.
I think it'd be a good point to ask now what kind of meals you'd eat normally and what you'd drink and such to try and find out what the balance is in your body currently.
Also the frail bones, are they a result of you not being able to move properly do you think? If its something else that can be found out too. I just didn't read on weather dystonia can lead to someone having frail bones. Didn't see that part in there.
Also to any others whom might want to comment, I don't have a lot of experience with actually diagnosing things just yet. And it'd be appreciated by me if others also had ideas how to deal with this kind of problem and posted them.
