my daughter had severe chest pressure and passed out in school yesterday.  She suffers from anxiety, but never anything this severe.  The hospital did an ekg, blood work and cat scan which all showed nothing abnormal...Could this have been a severe anxiety or panic attack?
Degree understand your concerns went through your details. I suggest you not to worry much. From the description it is very difficult to have a proper diagnosis. But I can assure you that pressure over chest and resultant vomiting is possible as an after effect of anxiety / panic attack. But you need to confirm. First consult a physician and then a psychologist. If you require more of my help in this aspect, Please post a direct question to me in this URL. http
