Hi, didn t expect to get a real person, but since your are here, I will tell you about symptoms I have been having. I think they are panic or anxiety attacks, but who knows. I get a tight feeling in the back of my head that moves to my temples then down into my throat and eventually down the middle of my chest. I get very emotional when this happens and after all that, I can t catch my breath and my heart beats really fast. It usually goes away in 2 or 3 minutes, if I can sit down and concentrate on my breathing. I recently had an MRI and my heart was found to be OK......any ideas????
