Muscle Tremors and Anxiety: Anyone Else?

Anxiety with muscle tremors/tensing/tics?? Does anyone else experience a anxiety/panic attack that produces muscle tremors? For me it’s usually a silent attack, I can sometimes recognize that I’m anxious, but it usually doesn’t cause hyperventilation, a general “panic” feeling, or anything like that. I usually just experience chest and/or arm pain, chest pressure and/or discomfort, and then the shaking and tensing starts. This usually happens once every few months, my usual anxiety doesn’t cause this extreme of symptoms. These also usually occur at night time when I’m relaxing or getting ready to go to bed. Has anyone found a way to stop these? Or reduce duration or severity? I don’t take any medications for anxiety anymore. I’ve been off them for 1 1/2 years (if that helps any?)?
