Hello

28F, almost 29 years. Last June I started twitchingnin calves which already body wide after googleing and panicking. History of GAD and health anxiety. Obsessive exerciser and runner. 

Well I panicked over A*S. And to this day I am still twitching. But my newest fear is that its getting worse because ky left hand which is my dominant hand, has become so stiff and always and that arm and hand twitch. Thumb and forefinger feel tight and stiff the most. Thumb feels shaky and jerky, like it doesn't move smoothly. No weakness though. 

Can anyone relate, could this all be in my head?
