I am so, so scared.My twitching is sone mad. My left shoulder has been twitching for a week violently in several spots and the "firing" seems to be affecting all the limb and also the back.I had twitches before, but this is something truly amazing in its intensity.To make the *beep* worse, my mum has been diagnosed 2 years ago with PSP or other form of Parkinson Plus syndrome. She went to the best Neuro, or presumed to be so and there is some form of concensus. She is in her early '70s.Now, you would say, it is well more than 6 years that I have been twitching, but guys, wow...This is something. And the flare-up, or whatever this is, did not take place at any time of specific stress or anxiety, this is for sure. Now, I am anxious.
