Could This Be A New Dystonia or Parkinsons?

I previously was diagnosed with 2 types of dystonia (cervical (2021) and blepharospasms(2016), and had a TBI (subdural hematoma about 4 years ago). Late in July, I developed a jerk motion in my wrist, which happens sometimes at night sleeping and or may start up from activity such as cleaning. Initially bouts lasted minutes to a few hours; but lately it lasts as long as 17 hours with jerks occurring seconds apart. The same arm has multiple problems: bursitis, a slap tear, rotator cuff tendinosis, and a frozen shoulder (adhesive capsulitis). The jerk symptoms started a few days after doing light-weight arm exercises (eccentric stretches).

I cannot sleep for it, despite having years of fasciculations which interfere nightly with my sleep--yet I am able to drift off. Not so with these jerks--it literally wakes me up and prevents me from falling asleep. Anyone out there have such a problem? It will be months before I can meet with my neurologist again. I have been diagnosed with Essential Tremor as well, but ALS is not suspected. Gabapentin, which I take for other issues does not seem to help.
