Hi Jackie   I can't answer the question about TIA's but I can tell you that some Migraineurs experience symptoms similar to yours during the aura phase of a Migraine attack. There are actually four phases of an attack: prodrome, aura, headache and postdrome, but not everyone experiences all phases. I don't have aura. You can read more about that HERE.   Acephalgic Migraine, or Silent Migraine, occurs without the headache phase of a Migraine.    Seeing a Migraine specialist may be the best thing to do, because they are the experts in treating patients with Migraines and headache disorders. We have a list of patient recommended specialists you can see by clicking HERE.    Good luck Nancy
