My husband has been experiencing left hand pinky tremor off and on since August. He saw a MDS a couple of months ago who said it sounded like it could be dystonia, but to come back in 6 mths if the tremor had not gone away, or if other symptoms developed. He has since had the same off and on pinky tremor and has also experienced one episode of foreman tremor (left) and has had one chin tremor. He is otherwise very healthy. We have noticed that the tremor seems to be more frequent when he is experiencing stress. Does this sound like early warning signs of PD?
