This is a new sensation I have with my panic attacks/anxiety...it feels like the right side of my neck gets really tense, like it's just about to cramp. Of course the first time I felt this, I went into a complete panic attack. I thought it was anything from a stroke to an anuerysm. I think my constant anxiety is just causing me to have all of these aches and tense-ness (?). Anyone else have odd sensations?
