Hi Sammi. I have this too. Even had a c-spine xray once because of it. Usually when it happens it goes on for weeks and I have sinus pain too. During those weeks the anxiety symptoms are much stronger. I haven't been able to find anything to help on this one.
I was wondering if anyone else experiences extreme tension in the back of their head and neck as a symptom of panic or anxiety? Geez I hate this feeling! It makes me feel like my head might just break off or something. Its scary!
Sammi
