To answer the question posed in the subject, I believe it can. When I first came to this board I had a list of 150 symptoms. My main ones besides the twitching were dizziness, trouble swallowing, sweating, severe flushing, tremor, migraines, loss of peripheral vision, night terrors and chest pain. The only proof I can offer that these were all anxiety related is they don't exist anymore. Since my anxiety is being treated and at a manageable level, I don't live with these symptoms every day. The moment I start to get anxious though...BAM...they return. I believe most frustrating for me was believing that when my anxiety was down my twitching would disappear. I experienced a second wave of panic when all the other things disappeared except for that. I twitch nothing like I did back in August and September, but they are still there and they do flare up from time to time. I have also gained things I didn't have when this all started: buzzing, tingling, jerks, hot and cold sensations and various other sensory issues. Perhaps they were there all along but my mind didn't recognize them with all the other junk I had before. I doubt I'd notice buzzing when I felt like I couldn't breathe and had severe chest pain...know what I mean?At any rate, the more I deal with my anxiety and do things good for myself, the less I notice all of it. I'm not constantly scanning my body for every little feeling which makes most of it fade away into the background. I still have those days when the stabbing sensations and tingling is at the forefront, but at least I don't send myself into a panic over it anymore!Frances
