Thank goodness I haven't ever experienced such pain with my panic accacks I do have severe physical symptoms like uncontrollable shaking, sweating, rapic hart beat... that could last almost a whole day Until I seeked treatment and med's They do help These attacks come out of nowhere... but I have now learned what triggers them and how to treat the attacks The attacks were so severe.... I was exhausted and had to go to sleep, just to recover So.. in a way I now know when to take the happy pills. My DR and T are now on speed dial and have become quite good friends You are not alone.
