I have been experiencing a feeling as if I am bobbing, swaying, and vibrations inside my body. I have had this for four years now. I have been to physical therapy and to a psychologist and has not helped. Sometimes family can see it when I stand up my legs kind of sway but other times I feel like I am being pulled from all different sides. I really am at my wit's ends with this movement disorder. Can anyone shed some light on this? Thank you.
