dear Want to be,
No one can replace the expertise of a physician; however, I experience similar symptoms when I have panic attacks. I even experience those symptoms when I am just overly nervous and not necessarily having a full blown attack. The sides of my neck often hurt so badly and are tender to the touch. I have learned that I tense my upper body very tightly when under stress and this causes the pain in my neck, shoulders, arms, etc..... Especially if I'm sitting for a long period of time in front of the computer or at my desk. My posture is horrible and doesn't help any.
If the symptoms continue you may want to check with a physician so he can determine what's going on for you. You're not alone---hang in there.
