I have an enlarged or herniated thorasic Diaphragm. I started having trouble last summer when I have episodes of a strage feeling behind my breastplate somewhat akin to when one is scared. I can burp several times and it will finally go away. It seems to be more prevalent in the morning (9am to 10am). My doctors can't seem to find a real reason for these uneasy feelings. My blood pressure and ekg's are normal. Sometimes I almost pass out. The situation is very unnerving and I would like to find someone who could deal with the problem and give we some way to alleviate it.
