Yesterday i had the worst headache ever went to er and they said it was a migraine i suffer from them but i have never experienced anything like that before, i also had flares on my vision but they didnt do any testing. im still having some pain?

Migraines: There are various kinds of migraines, some involving the eyes. Please see your eye doc to rule out any eye issues and continue to see family doc. Some hospitals have headache clinics, other approaches include food sensitivity lab testing. Biofeedback can be very useful, usually done by a specially trained clinical psychologist. Peace and good health.
