Body movement

Can anyone tell me why at times I have a lot of head movement. and at at other times I have a lot of body movement.the only way I seem to be able to control the body movement is by lying on the floor.

It sounds like Dyskinesia, or Dysco as I call it you will probably have heard of it, unfortunately its one of the more irritating aspects of PD and can be very frustrating especially if you are trying to do something that requires precision, when you are suffering try to stay calm , play some of your favourite music, if you can, it will pass but you have my sympathy Angel, its not nice .
