I have read that a tingling sensation (pins and needles feeling) and numbness can be caused by anxiety. In all of my years with GAD this is not a symptom I have had until recently. 

I am just wondering, is this something that happens during a panic attack or moments where one is feeling very anxious, or can it happen when one is feeling relatively calm? 

I have had it happen in my arms and hands and recently it happened on my face. It was during times I felt pretty calm though.

If it purists t I will see a doctor, but just wanted to know if it can happen when you are feeling calm.
