I have went to you tube and watched a few videos and one video was very similair to my symptoms. She was having arm spasms just like mine, however she couldnt sit still either. IN most videos their symptoms were worse than mine. And mine come and go but guet worse when i try and type, or grab the mouse, or try and write and if i get upset, it gets really bad an dmy head starts turning to the left. All this motion is making my neck worse and my shoulders and back muscles sore. Odd I know. I am not sure that the injections did cause it, but i found where 2.7% of chorea (induced) cases filed with FDA were steroid injection related. I just had one in my neck last week and things got bad this week. I thought I was better today, really, until I sat down to do research online. I took 2 videos to show my Md and Neurologists. Is that a good idea?
