I'll give you a little info, but do what the neuro says no matter what
I say here.
Tardive dyskinesia is a
dystonia, you feel it especially in the throat and lower face, and, as you said, taking Seroquel for a long time can cause the muscles to tighten up, even long after it has been discontinued. On top of that, some anesthetics and adjuncts can cause dystonia, and these include Versed, Propofol, and Droperido.
