I have tons of neuro symptoms, too. Twitching. Dizziness. Head pains. I went through a full workup a couple years ago for it during my ALS anxiety phase. One day I remember twitching over my entire body.
It can most definitely be related to anxiety, which explains why your symptoms didn't go away...
I remember the neurologist telling me "You are always on the look out of symptoms, but what you don't realize is doctors look for signs, too. And I could tell when I saw you walk from the waiting room to the exam room that you were ok."
Focus on lett gint he anxiety float through you instead of latching on to it. It's hard...I struggle too. But the symptoms are commonly felt by others on this board.
