Hello,
I feel your pain! Ive been there! I also has Panic Disorder and had to take meds for this samething. Feeling like you are going the die and heart racing and dizzy and wanting to pass out, all are systoms of Panic Disorder. However the Pains that you still face are diffrent. After reading you fourm, I think that you should have you Thyroid Checked! Some of the systoms you are discribing can be related to an over active thyroid level.
Best Regards,
Wayne
