I am a long time sufferer of HA and GAD and have had twitches for years but not much lately. I have been doing OK lately but last night was a really anxious period for me worrying about my relationship with my wife. I was and still am a little bit anxious. Now today I have massive twitching and some lightheadedness. Could this be delayed from my high anxiety from last night or should I be worried? I am not on meds and I am 40 yr old.
