I ended up here accidently was looking for movement disorder wala here I am.
I was told I had a psychogenic movment disorder in my leg a few years ago at that time it was something the neurologist induced in his office I could not see what he was doing as I was laying down and he was over me blocking my view... but I sure felt it and asked him what it was that was the first time I felt uncontrolled movement that I can think of... since then I have been dx with multiple chemical sensitivity and have a full blown movement disorder not other wise defined as of yet as I am in the 2 year waiting list widow for assess a movement disorder... it looks like huntington's to my family doctor. yes I know psychogenic is in your head but you don't control it and I have not read much about it cause i think it is bs... cause I have lived with cfs fibro for 30+ year and taken a lot of drugs and tried a lot of things.. mostly brain drugs ssri... snri they can make you crazy... they did me...now I am very leary of putting myself thru nonsense cause a doctor wants to get his name on a paper somewhere or do a stupid study ... no thanks not trading my life for your academic benefit. I want to know... I do but blaming my mental health cause your too closed minded to keep looking for the cause is not going to help anything and will likely further damage me... it will surely damage my heart to have to go thru another it is in your head scenario... so I am done with it. My choice and knowing what I have been thru already with psych crap this is the only choice possible for me.. a very personal thing and I have not read this entire thread as I likely should before posting I know this... yet I may have something of value to offer off the cuff...
"Recently, I have been working as part of a team of experts evaluating patients injured from a refinery release in the town of Crockett (investigating the results of the Catacarb spill of August-September 1994) adjacent to the Carquinez Bridge in northern California. UNOCAL had a leak in their tank which grew and released Catacarb and other toxic pollutants which drifted onto two entire towns. Over 700 patients have come into the Good Neighbor Clinic in Crockett (paid for but not run by UNOCAL) because of symptoms; more are on the waiting list. Patients in general have eye-damage; breathing problems; immune abnormalities; rashes; increased mole size; skin tags; possible neuroendocrine disorders (abnormal menstrual periods); neurological abnormalities that include memory, concentration, decreased verbal fluency, and motor problems; and one has a serious movement disorder. Many, but not all, have developed MCS."

There are not many documents that point out that mcs (multiple chemical sensitivity) can cause movement disorders that do not show on testing what would normally be on testing of a person with a movement disorder.
Of late I have learned that MCS is now thought to be an associated with CFS and fibro... which I have had 30 + years. Maybe after a long time you get mcs.. I don't know.
I do know that there is a treatment options
