hi I have yet to get a diagnosis, and I have very mild symptoms, I am currently waiting to have a Datscan in a couple of weeks. All I know is I do not feel the same with what I thought was weakness on one side, but my neurologist says it is slowness, and if it is early symptoms of Parkinson's I will not need to take any medication as yet. I will have to wait and see as I've always attributed everything to a trapped nerve as I have pain and stiffness, for over a year now in my neck,but the mri shows mild stenosis with no pinched nerve,and the neurologist says it usually starts in the shoulder rather than the neck?
