I am not sure it is causing any
TMJ issues. Lets put is that way it is not the cause
for TMJ. Dystonic reactions (ie, dyskinesias) are characterized by intermittent spasmodic or sustained involuntary contractions of muscles in the face, neck, etc. Which can mimic the symptoms of TMD. I am not ruling out TMJ/TMD, therefore I recommend that you have a consultation with a TMJ expert in your area by visiting www.top3dentist.
