I have had symptoms of dystonia in my feet,and tardive dyskensia in my jaw. I have also had twitching,jerking and myoclonic jerks while I was on oxycontin in the hospital. also I have an unbelievable startle response. I just about hit the roof with a loud noise. I have corresponded with people who have very similar occurrences, but they appear to wax and wane. One week they are there,next week they are a bit different or even gone.The more I stress about them the worse they seem to get. When I finally accept them they dissappear. Go figure?

I hope you are able to figure this out,as the pain aspect doesn't sound very good.
