How About Functional Neurological Disease/disorder. Any Help There, I Have

How about functional neurological disease/disorder. Any help there, i have been diagnosed with this, i get bouts of muscle jerking, head, arms, and legs, mid drift area, sometime so bad, and they tell me there is nothing they can do, if i sit down on a chair with arms, it triggers, if i lean forward and raise my arms, it triggers, and so it is in my opinion movement triggered, when it is bad,it is really bad, then it seems to go through its routine and then leaves, until i make a movement that it doesnt like and then i am off again, it affects my voice, ad sometimes my throat feels like it cannot swallow, for a few seconds, It has been eight years now since it started quite out of the blue, Any suggestions , other than. Learn to live with it, you will die with it, not from it.
