If you have migraines, you must see a cardiologist. He must preform a TEE on you. It is a camera down your throat, 20 minutes, you wake up, no fuss. If it detects a hole in your heart that doesn't close after birth you may be able to be fixed of migraines. My fix was an overnight in a hospital after non-invasive surgrey to put a plug on the hole, no open heart surgery. My daughter had migraine symptoms, she did the TEE, same problem, she got hers fixed too, she now has no migraines. My grandaughter has the problem also, she is 3 and has to wait for her fix also. I understand that blood gets filtered by the lungs, the hole bypasses some of the filtering and a clot, even small can go to the brain. The only medicine I am on now is one enteric baby asprin, and vitamin E. I had all the chemical symptoms for 40 years, caffeine, cheeses, MSG, flasing lights, etc. No problem now, I do stay away from MSG and caffein as I believe that certain foods or additives can promote small clots. Bottom line, I am fixed, no migraines. God is Good ! -Bill
