there is such a thing as thoracic endometriosis....for those of you women who are of child bearing age......with chest pain.....
tried to search on thoracic+epilepsy......4 pages worth...biggest # where related to thoracic vertebral fracture related the the seizure....
i have heard of abdominal epilepsy....but it was confined to that area.....not resulting in generalized seizure.......perhaps this chest sensation is part of your "aura"....??
oh dear, i just went back and reread....had missed the part about feeling punched from the inside out......if i were you, i would be requesting a Holter moniter....to see what is happening to your heart during these episodes....
